I just created a small form and spreadsheet and CopyDown worked for me.
I usually use an arrayformula but when I need copy and paste the result, CopyDown is my tool.
Select a new destination from the form.
Insert necessary columns and copy and paste the formulas from your current spreadsheet.
Copy row 2 and insert a row 3. Paste into row3.
Delete all but one formula and go to step 1 below.
- Test CopyDown.
- copy another formula from row 3 and paste in row 2.
- repeat step 1 and 2.
You may find a formula that breaks CopyDown.
