Margin Accounting: Financial Statement Version YPS2

Dear Experts,

My client would like to have a custom reporting structure for their contribution margin report.

So a presentation up to contribution margin IV should be possible, furthermore the functional areas should be used instead of the g/l accounts!

Question: is it possible to copy the YPS2 structure and adapt it accordingly? Or is YPS2 fixed in relation to the delivered reports and the reports would then no longer work correctly?

And: either g/l accounts or functional areas can be assigned to the positions of the P/L? Is this correct?
