Revenu Generarion to be controlled at top task

Hello

We are on 11.5.10.2 (Pack M) and use top task billing functionality with customer at top task.

This means I can control Invoice method at top task (Event / Work)

simillarly We also want to control Revenue generation at top task.

In a specific case we have to accrue revenue on 'events' for one task & on 'work' for other task in the same project.

I doubt if that is possible with std functionality. I there any way around to resolve this??

Thanks in Advance
