An alternative approach MIGHT be to use the clone command.

If you clone a control which is already part of a group, then it to will 
be part of that group. So if there is at least one initial button in the 
background group, you could clone it and then modify the name / script 
/etc. of the newly created one.  Only an option if there is an initial 
background group with an initial button.

If you follow Bob's approach of ungrouping and regrouping, you could add 
a filter command to allow the option of having other controls which are 
not part of the background group (if you need that). Something like

on mouseUp
  addToGroup "card id 1002", "My Group", "My Button"
end mouseUp
on addToGroup pCard, pGroupName, pButton
  -- Adds button pButton to the group pGroupName on card pCard
  -- assumes controls and groups have unique names
  local L, tControls, toDo
  repeat with L = 1 to the number of controls of card pCard
    put the  long name of control L & cr after tControls
  end repeat
  filter tControls with ("*of group " & quote & pGroupName & quote & "*")
  ungroup group pGroupName of card pCard
  put "group " into toDo
  repeat with L = 1 to the number of lines in tControls
    put word 1 to 2 of line L of tControls & " and " after toDo
  end repeat
  put "button" && quote & pButton & quote after toDo
  do toDo
  set the name of  last group to pGroupName
end addtoGroup
