Merge same properties in application.properties and application.yaml

I have two properties files: application.properties:

spring.datasources[0].url = jdbc:postgresql://localhost:5432/earch
spring.datasources[0].username = postgres
spring.datasources[0].password = 
spring.dataSources[0].driver-class-name=org.postgresql.Driver
spring.dataSources[0].liquibase.enabled=false

spring.dataSources[1].tenantId=db4
spring.dataSources[1].url=jdbc:mysql://localhost:3306/test_liquibase?createDatabaseIfNotExist=true&allowPublicKeyRetrieval=true&useSSL=false&useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC
spring.dataSources[1].username=root
spring.dataSources[1].password=
spring.dataSources[1].driver-class-name=com.mysql.cj.jdbc.Driver
spring.dataSources[1].spring.jpa.hibernate.connection.charset=utf8
spring.dataSources[1].spring.jpa.hibernate.connection.useUnicode=true
spring.dataSources[1].spring.jpa.hibernate.ddl-auto=validate
spring.dataSources[1].spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5InnoDBDialect
spring.dataSources[1].liquibase.enabled=true
spring.dataSources[1].liquibase.change-log=classpath:db/master/changelog/db.changelog-master.yaml

and application.yaml:

spring:
 dataSources:
  - tenantId: db5
    url: jdbc:postgresql://localhost:5432/db4
    username: postgres
    password: 
    driver-class-name: org.postgresql.Driver
    liquibase:
      enabled: true
      change-log: classpath:db/yaml-change/changelog/db.changelog-master.yaml

and config file:

@Bean(name = "dataSources")
    @Primary
    public Map<Object, Object> getDataSources(DataSourceProperties dataSourceProperties) {
        return dataSourceProperties.getDataSources().stream().map(dataSourceProperty -> {
            DataSource dataSource = DataSourceBuilder.create()
                    .url(dataSourceProperty.getUrl())
                    .username(dataSourceProperty.getUsername())
                    .password(dataSourceProperty.getPassword())
                    .driverClassName(dataSourceProperty.getDriverClassName())
                    .build();
            return new TenantIdDataSource(dataSourceProperty.getTenantId(), dataSource);
        }).collect(Collectors.toMap(TenantIdDataSource::getTenantId, TenantIdDataSource::getDataSource));
    }

now parsed only yaml properties. If drop yaml prop, parsed properties from application.properties

is it possible to merge this properties from two files to dataSourceProperties?

create the same DataSourceProperties class for example, DSProps:

@Data
@Component
@ConfigurationProperties(prefix = "spring1")
@PropertySource({"application.yml"})
public class DSProps {

    private List<DataSourceProperty> dataSources = new LinkedList<>();
}

@Data
@Component
@ConfigurationProperties(prefix = "spring")
@PropertySource({"application.properties"})
public class DataSourceProperties {

    private List<DataSourceProperty> dataSources = new LinkedList<>();
}

and in the method getDataSources add one line:

dataSourceProperties.getDataSources().addAll(dsProps.getDataSources());

of course in the application.yaml prefix must be different
