Adding Proficiency to attacks rolls for a Class Activities?

[Faolan the Azure Abjurer]

Simple query.

When making an Activity entry on one's character sheet, under Actions/Effects, the activity requires an attack roll. Is there a way to make it so it applies the proficiency bonus from the class's Spell/Class Proficiency?

The exact activity in question here is a Kineticist's Elemental Blast.

The damage works perfectly fine, but I can't get the Cast action's attack roll to take the character's level and proficiency level into account.

I went to program all the Impulses as activities, since I couldn't get the Ocean's Balm healing to scale off of odd character level when coding them as a spell class, since the kineticist has no caster level and there doesn't seem to be a way to tell a spell class to scale off of character level for caster level.

The attack action accepts only a named Attack proficiency. As a work around you could manually add (and maintain) an entry into the Attack proficiencies section and use that.

Works perfect. Thank you!
