Is it possible to create a quadruped character using the A.R.T tool?

I know that the tool is optimized for bipeds, but is it at all possible to add legs to the initial rig and sort of piece together a decent quadruped? I would appreciate any advice or if somebody could point me to a place where I can get more information on this like possibly a tutorial. Thank you!

Probably could do quads after all there are four limbs where a “biped” is only walking on two.

Been done more than once using Character Studio and C.A.T so it’s something to Google.
