Animating bones in models, would it be wise to reset bones...?

I've contacted a modeller to do a model for my game. However, I was wondering when I'm manually adding animations, say for example I have a walk animation and I want to shift to running animations like so:



The thing is that when I go to add a new frame, it "copies" the bone animation from the previous frame, but I want to start fresh for the models' new animation (ie. reset back to where it was before any animations were made).

Would I use the A6 MED "Reset Bone Animation" tool to reset the bones so I can start a new set of animations without affecting the current ones? Or is there another tool I can use?

how 'bout create an initial frame before you start create "idle0"(etc: pose0,idle0,walk0...), its the pose where the model weren't animated at all, then when you create other frame , just use "pose0" for it source....

I like that idea, peank. I suppose it should work. Thanks!
