Hello Robyne,
When you say the second sheet is 'pulling data' from the first, I assume that this is just formulae that refer to the first sheet. So, if you select sheet1, hold shift and select sheet2, you have selected both sheets. Then right click on one of the tabs and a pop-up will appear that includes an option to move or copy sheets. Open that and tick the create copy box. When that is done you will have new sheets names sheet1(1) and sheet2(1) which you can then name to sheet3 and sheet4 and all the formulae references on sheet4 will be to the cells in sheet3 in which you will be able to enter your data for the new scope. Just repeat as required for as many scopes as you need.
If this isn't what you want, maybe if you could post a (sanitised) sample workbook, it might be possible to help further.
