Magic Initiate (Bard) updated for 2024?

I was trying to make a Magic Initiate (Bard) feat, but updated for 2024 like the ones for Cleric, Druid, and Wizard, where you can choose which modifier you use to cast the spells. I was able to make the options to choose, but I can't seem to figure out how to make the available spells based on the choice. I imagined there would be something within the Option page to provide a spell list, but it only allows for an Action.

Is there something I'm missing or is it just not possible at this time?
