How to optimize/decimate/LOD ActorGroup in iClone 8.7

I have a large scene in Unreal Engine that I’ll need to populate w/several actor groups w/animations from the “Social Actions” pack. Please tell me there is a way to optimize/decimate or increase the LODs for the entire group in iClone.

Please DO NOT tell me I’ll have to send each individual character to CC5, optimize/decimate there, then send back to iClone. I tried the roundtrip and noticed once the character is sent to CC5 and back to iClone, it strips out the original animation and replaces it w/the ‘idle’ animation from CC5.

Ok - when roundtripping from iClone to CC5 and back, when sending back to iClone from CC5, it pops up and asks to overwrite the animation; clicking cancel preserves the original, yet still updates to the optimized character from CC5 (I thought ‘Cancel’ would cancel the entire process outright.)
