Graph Editor - Post Behavior > Keyframes

[jds580s]

In the graph editor I have some post behaviors set to "Offset Repeat"

Now I would like to add a slight variation after repeating a few times.

Is there a way to bake the offset repeat, but not on every single frame, but rather only the keyframes that are being repeated?

I hope that makes sense.

In the past I have baked, then tried to reduce keys, but that gets really old after a while.

Thanks for any help!
