I can't really think of any way this could work automatically.
Messages are only sent to the objects within a group, or directly to
the card if the mouse isn't over a control in the group...

Use a rawKeyDown handler: there's a different key code for up and down
wheel and only if these messages aren't handled does the automatic
behavior kick in.
