Is it possible to make Entity Framework separate scaffolding mapping into multiple classes, instead of auto-generating all mapping into a single file?

I am running the Scaffolding command for Entity Framework to automatically create classes based on my database DatabaseName:

Scaffold-DbContext 
    "Data Source=COMPUTER; Initial Catalog=DatabaseName; Persist Security Info=True; User ID=USER; Password=PASSWORD; trustServerCertificate=true;" 
    MicrosoftEntityFrameworkCore.SqlServer -OutputDir Models -force

However, I am noticing that Entity Framework puts ALL of the mapping in that single context file DatabaseNameContext.cs. For me this means 5000+ lines of code of mapping all in one file, and it's just not as readable and 'clean' (separated) as I would like.

What I would ideally want is to create a Mapping folder under my project and have a map file per table, like so:

UserMapping.cs, Purchase.cs, Product.cs etc where inside of each is the relevant mapping for that single table.

Is there a way to do this automatically using Entity Framework, or would I have to manually do this to achieve this result? Thank you.

Specifying -ContextDir and -OutputDir separately should give you the desired result. They can be the same actual value if needs be. You can also use EF Core Power Tools if you prefer a GUI. This also provides some features that EF Core doesn't, like scaffolding of Stored Procedures.
