Help with adding modifiers in homebrew

I can't figure out how to add the wisdom score modifier to charisma check scores in a homebrew subclass im making. Can someone walk me through it?

The tools probably cant do what you are trying to do (which sound OP), but could you be specific about what you are trying to do?

What i'm trying to do is enable the class to add their wisdom modifier (say a +2) to persuasion, deception, and intimidation.

Modifier Type: Bonus

Modifier SubType: Persuasion

Ability Score: WIS

- Repeat for the other skills.

Thanks!
