smart bone & cycle keys

[martin_mrt]

Im having this quick thought for a setup which I would love to bounce off the Moho Forum:

I'm Working on Dropshadows of my Characters. Its a seperate layer which gets its X postition from the Charachters Center of mass. That works, but now I woul love to have some internal Motions via pointanimation while the charachter is walking. I thought about some "automatic" setups already but now had the idea that maybe a smartbone toggeling between still and motion could be an option. Is it possible to integrate a cycle into a smartbone?
can it cycle in one action and be still in another action (eg. to the left still and to the right with cycle)?
Would this produce a toggle switch for an animation loop which i could turn on and off at different times in the animation?
