3DS Max Bone-Related Question

[Carpaccio]

As usual google and other various search engines prove to be completely useless in regards to a rather specific question I have. Now this may seem a little odd, but in a few projects of mine I've received a few 'pre-posed' DAE's with bones and such. Currently, I have to spend a ridiculous amount of time resetting every bone rotation back to 0,0,0 to return the model to it's base pose. Now I've got a significant amount of models and doing this manually to every single one would be incredibly time-consuming and I'd get very burned out very quickly. I was hoping someone here could inform of a way or perhaps supply me with a script  or plugin that would hopefully automate the process of resetting the rotation of all the bones (or is it pivots?) to 0,0,0 so I can export in 'bind pose'. Can anyone help?

Do note that all rotations at zero do not make a (proper) bind pose.

MaxScript:

Code:

for o in objects where classof( o ) == BoneGeometry do
(
   in coordsys ( transmatrix o.transform.pos )
   o.rotation = quat 0 0 0 1
)
