How to create a copy of a formula
Save time and create new formulas easier by making copies. A copied formula is separate from the original, and any changes made in one will not affect the other. Just make sure to update your dashboard widgets if you want to visualize your metrics with the new, copied formulas.
Go to Formulas and open a formula.
Click the little arrow in the Actions button in the top-right corner, then Copy to new.
The page will reload, and you will see the formula title with (copy) appended to it. This is the copied formula, but it's not saved yet.
Update the formula according to your needs.
To finish, click Save in the bottom right.
