Creating loop+transition regions using the scripting API?

Hi! I’m wondering if there’s a way to create loop regions, transitions, and transition regions using FMOD Studio’s scripting API?

I’m able to successfully create a marker track by using Event.addMarkerTrack() and then calling MarkerTrack.addNamedMarker(), but so far I haven’t found a way to add loop or transition regions. Is this functionality available / am I missing something in the Scripting API Reference?
