ZScript - Selections sets for Polygroups?

Hi,

does anyone know if there is a zscript that allows one to make selection sets of polygons?
And I am not talking about polygroups. I am already extensively using polygroups when sculpting characters, but
I would like to, for instance, instantly single out the eyelids with a “selections set” to adjust them to the eyeballs
and not being forced to lasso- a/o ctrl-shift-click - HIDE the other polygroups whenever I want to isolate

Thank you.

Cheers,
Michael
