3ds Max :: Make One Shorter Animation Loop Within Longer One?

I want to make one shorter animation loop within a longer one. Example would be a rotor of a plane spinning when the plane flies by, or a parameter of a material looping within lets say 15 frames (e.g. UV offset changing in cycles) while the whole walk cycle is 60 frames long. If it is a simple property that has to be changed I could simply key in a multiplied value (in the previous example I could offset the UV by 4.0 so it would loop 4 times) but this wont be a solution for more complex stuff.
