Multipule animations for each node on a machine

[swillo]

Currently you can only have one animation working for a "machine".
It would be helpful to be able to assign multiple animations, and chain their playback, to each node of a machine. This would allow much more variety in actions on machines. Like different moves on training dummies, or idle characters playing cards around a table. It would also allow sparing mats where the opponents could face each other, or surgery tables where your doctors could add their medical skills to a units healing or perform plastic surgery, or having a table for food storage were characters come and sit for a meal.
