Place group on all cards, after already duplicated

[Christopher Mitchell]

Howdy,

Just wondering if there is a way to place a group on all cards - if you 
realized after you've already duplicated and individualized all cards 
in a particular stack with an original, but deficient, set of controls. 
  kind of like "oops I really should have put a "close" button in this..

Just off the top of my head, adding that extra control to the 
originally duplicated group should do it, right?

on the other hand, if you wanted it to be a separate group, one might 
have to do something like (this is very mocked up)

repeat with i = 1 to the number of cards
   place group "foo"
end repeat

I don't particularly want to add it to the original control group, but 
I don't want to edit each individual card either. the UI makes 
accessing card elements and doing multicard edits or even multicard 
deletions difficult unless you write a small script to do it.

or maybe I just don't know what's going on!

Yours,
Chris
