Forecast on a fixable Key Figure

Hello All,

Here is my point:

My 'Corrected forecast' key figure is a fixable key figure. If a cell is fixed at the forecast level, then the forecast can not be saved on all the horizon. Is there a way to make that only the fixed cell is not saved and all the other ones are saved ?

For example, users may know that on month 'M', the demand will be 'X' and they don't want the next forecast run to delete this quantity X.

Thanks in advance,
