is there any trick to link color art (outside peg) to a peg, so color art can follow peg movement like in premium?

Hi, i’m trying to make cutout for a character in toonboom advanced, and i kind of stuck at thigh or leg joint to body.

I want to make body and leg color suit connected.

I only know 1 trick in premium to split layer (like color art only or line art only) and connect it to peg and u can set it in node view so that the color at the front of the body.

is there any trick to make this could happen in advance?
