Excel Copy/Paste Sheet and Rename Cells
Solution 1:
Instead of clicking the top left of the sheet to select all cells and copy/past them, I needed to right click on the sheet and select 'move/copy'. When copied through that method, the cells keep their name, and excel always resolved scope by the most local variable first, so the cell names are not unique, but by default use the local cell name before the global workbook cell name.
