Help with some key frames

[Failed_Hero]

I have about 5 skopes and skoped keyframe sets that would be perfect if i could figure out how to add nodes to an animation sets.

Some of these are as simple as adding the gun nodes to the idle, melee_idle, run, hit and stunned, get up forward, get up back, hover, and hover pain animations.

Others are a bit more complex but if some one could help with the knowledge, I could do the work.
