This is in the standard product no need for an extension.

Don’t think of the spells section of the actions tab as just for spells. Add a "spell class", then call it "Abilities" or something like that, then add a 1 to the level 1entry under the spell class details so that a spell header opens. Then you can add new "spells" to that list and attach actions to them - but they’re not spells.
