BP incorporated into a reporting system

Hello,
For large files, we need to make a forecast but also to produce a projected balance sheet for the banks. It would be a good idea to add, in a reporting file, in the Balance Sheet tab, to have 'Forecast Balance Sheet' in addition to the Historical Balance Sheet.
Forecasting is of course done in reporting, i.e. by importing excel files, etc...
But it's not the same in a BP file.
We should "just" add the "Balance sheet forecast" page to the reporting so that we can have our forecast in Balance sheet format as well.
