When choosing to make a superscript letter in a table in Powerpoint, the automatic percentage is set to 30%. This raises the superscript too high and is usually touching the line in the row above.

I would like the percentage to be either 10% or 20% and not have to change it every time I click on the superscript button. If I can figure out a way to so this, then I can use the keyboard shortcut and save myself a ton of hours at work.

Any thoughts would be appreciated and welcomed!
