Here is some tools I did in MaxScript to assist me in some boring and repetitive tasks in 3dsmax.

Petri's AutoRig is faster and more correctly to position the bones in a character, leaving the bones already renamed.
you can also create a simple rig and add the bones in the skin with just a single click.
