Cashflow Module: Forecast if Positions should have future Start Dates

Hi,

at our current client we are facing a big issue/problem due to a limited functionality in the cashflow-module:

When the Forecast Curve is set to  "Beginn Calculations at end of curve": Spends, the Start Dates of the single CBS-elements can not be changed anymore, Start Date is always equal to cutoff date.

This is, to be honest, just wrong. If you imagine a large construction project, which has a total time from 3 Years. There will be activities like Planning,which do start at the very beginning.

But for example Activities related to the construction will start after the planning phase, lets say in Year 2.
