Animating just an arm using DAZ / export replacer

Hello,
I have tried all free animation editors. Havent decided yet which one to prefer. If only all thse brilliant programmers would get together...

I like the reverse kinematics of DAZ very much. I use Escort DeFarge's export replacer which works great.If I understand correctly this export replacer adds/changes frame 0 to make sure all body parts are used. Now I'm wondering. Is it possible to make an animation that only animates an arm for example ?

Yes you can make an animation that only animates one arm. I don't know how to do it using those tools you mentioned though. I'm sure it's possible.

I wish we could merge and simplify all the programs out there into one SL animation program. *Throws coin into well.*
