Adding Spell-Like Abilities to NPC

[RBSealey]

I'm trying to create a Gug Savant, which adds 4 spell-like abilities that can be used once per day. I've tried various adjustments, and adding some levels of Adept. The former didn't help, the latter added too much to the monster's CR. I'm using the Bestiary Monster Creation race selection and building it from scratch. But for future reference, is there some way I could take a Gug and add spell like abilities without building a monster from the ground up?

Create a simple template in the Editor that bootstraps your four spells with the Helper.SpellLike tag. Don't know of a way without using the editor sorry.
