Adds a seperate pick proc to work on lists (#65178)

Because of how arglist() works, _pick was only working on args matching
the format pick(1, 2 ,3)

Because this is logic that happens inside pick itself, and I can't
figure out the proper way to actually pass things in, I've created
_pick_list so admins have a sane way to pick from lists.
