Can you add effects ( highlight ) to a group?

I have a character with many layers and parts. I want to group the character’s elements together and add a highlight to the group, instead of wasting time adding a highlight to each individual part (head, ears, nose arms, etc ) But when I try to do this, I get nothing.

So far the consensus is to attach my highlight module to the group’s master peg but again, nothing happens.

Draw a “Highlight-Mask” and connect it to the “Highlight-Module”…

perhaps you would use another composite module to pre-compose all the shapes, affect this with the tone via a mask, then plug the results into the master composite.
