Couple of ways.
1. If you animate your prop and save it, the animation is embedded into the prop.
Next time you load saved prop animation would play at the original interval at the timeline.
2. You may select Collect Clip range covering the animation part at the timeline for the prop and then right mouse click > Add to Perform
This would save motion externally but motion could be invoked with right mouse click > Perform. Make sure to use Reset Transform (zeroing rotation out before animating the prop).
In this case distribute your prop along with motion file.
