I have a question concerning routing workflow to Group.

Basic structure is that workflow goes to each group members task list and
each group member gets separately email noticication of the task.

However - the first person claims the task the task disappears from other
groupmembers task list (as it should). Now problem is that other members
have the notification and if they decide to react to the noticication - they
do not find anything from their tasklist...

My question is: How to route email message to email address stored to group
object instead of each users email address?
