I can't seem to figure out two simple idle-related issues.

1. How to make an NPC loop a certain handful of idles, for instance if i wanted it to not stop "dance" idling but use several random dance animations instead of just one.

2. How to make an NPC keep idling forever, for instance if i wanted one to lean up against the wall and remain that way, but be able to come out for combat and then go back to the idle immediately afterward.
