You'll want to use a Configurable. That'll be the tab they select each thing from. Bootstrap the configurable to the racial ability that says "you can pick two yadda yadda yadda."

Then each pickable ability is a Custom Ability (found under Class in the editor, but they're not intrinsically linked to classes). Those abilities can be linked to the configurable, and can each have their own descriptions, trackers, etc. and are viewable in the In-Play and Specials tabs, depending on how you program them.

The simplest examples I can think for you to look at would be the Supernatural Gifts tab. Supernatural Gifts is the Configurable, and all the gifts themselves are Custom Abilities.
