Is there any "animation manager"?

I am modeling a complex fighter plane, with hundreds of actions, from the cockpit, to the tail flaps and jet engine and everything in between. Is there any way I can save specific actions so I don’t forget/have to spend hours re-posing the craft every-time I want to change the shot?

pressing F near the action dropdown in the dopesheet will save it
NLA editor is for managing all the actions on the timeline
