Drawing program for BOM balloons

Hi!!

I have 2 sheets , one with master representation and the 2nd one is a simpler represntation i.e some parts are deleted from the 2nd sheet, otherwise everything else is same as the 1st sheet. But when i change the represntation from master rep to simple rep i end up losing the balloons as well.

Is it possible to use drawing program for somehow getting all the balloons from sheet 1 into sheet 2. I can edit the unwanted balloons later.
