Overriding FullCalendar calendar.prev and calendar.next behaviour

I have a calendar where one of the views is for 2 months. When clicking the Prev and Next buttons the default behaviour for this view is to skip back two months or skip forward two months. What I want to achieve, if I click the next button for example, and I'm viewing March/April,is to change the display to April/May and not May/June.

Is this possible?

I have actually managed to solve the problem as follows. I am using FullCalendar Scheduler with the following views -

			views: {
			resourceTimelineDay: {
				buttonText: 'Day',
				type: 'resourceTimeline',
				slotDuration: '00:05:00',
				slotLabelInterval: '00:30:00',
				slotLabelFormat: [{year: 'numeric', month: 'long', day: 'numeric', weekday: 'long'}, {hour: '2-digit', minute: '2-digit', omitZeroMinute: false, meridiem: 'short'}]
			},
			resourceTimelineWeek: {
				buttonText: 'Week',
				type: 'resourceTimeline',
				slotDuration: '01:00:00',
				slotLabelInterval: '2:00:00',
				slotLabelFormat: [{year: 'numeric', month: 'long', day: 'numeric', weekday: 'short'}, {hour: '2-digit', minute: '2-digit', omitZeroMinute: false, meridiem: 'short'}]
			},
			resourceTimelineMonth: {
				buttonText: 'Month',
				type: 'resourceTimeline',
				slotDuration: '02:00:00',
				slotLabelInterval: '24:00:00',
				slotLabelFormat: [{year: 'numeric',month: 'long'},{day: 'numeric', weekday: 'short'}]
			},
			resourceTimelineTwoMonths: {
				buttonText: '2 Months',
				type: 'resourceTimeline',
				duration: { months: 2},
				slotDuration: '02:00:00',
				slotLabelInterval: '24:00:00',
				slotLabelFormat: [{month: 'long'},{day: 'numeric'}]
			}
		},

I have created a couple of custom buttons to select prev and next periods. view3 is set depending which view button is clicked -

				periodPrev: {
				text: 'Prev', icon: 'chevron-left', click: function(){
					if(view3 == '2 months')
						{
						let currentStart = new Date(periodStart);
						let updatedStart = new Date(currentStart.setMonth(currentStart.getMonth()-1));
						periodStart = moment(updatedStart).format('YYYY-MM-DD');
						calendar.gotoDate(periodStart);
						calendar.render();
						}
					else
						{
						calendar.prev();
						}

and

			periodNext: {
				text: 'Next', icon: 'chevron-right', click: function(){
					if(view3 == '2 months')
						{
						let currentStart = new Date(periodStart);
						let updatedStart = new Date(currentStart.setMonth(currentStart.getMonth()+1));
						periodStart = moment(updatedStart).format('YYYY-MM-DD');
						calendar.gotoDate(periodStart);
						calendar.render();
						}
					else
						{
						calendar.next();	
						}

The standard calendar.prev and calendar.next is called if the view isn't '2 months'. Otherwise the date is manipulated and results in the 2 month view incrementing or decrementing by one month.
