A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
If you need to do that you should only have a single source and then make a pivot table out of that to view subsets or just filter to get the subset you want.
so to be clear, you would just have your single combined sheet of data.
it sounds like you want to be able to make a change in either location and have it reflect in the other location. You could probably do that with code, but it sounds like the long way around the block to me.
