Is there a way to quickly test a formula?

Is there a way to quickly test a formula is working correctly?

For example, when I build a formula in an item, sometimes there are multiple inheritances and I want to verify the output is mathing correctly. I have been doing a quick test take off to check it, but it would be nice if there was a test feature where the variables could be entered manually to verify it is working. Couple with this would be if it pulls the inherited values or checks that the inheritance is valid.

This would help veify formulas quickly without unnecessary sample takeoffs.
