WF: Reserve of work item not wanted.

[lj wf]

Hi,
 
I have a workflow step that sends a work item to 3
positions.  Once one person opens it, the work items
leave the other two mailboxes.
 
Can I prevent this so that the work items will stay in
the other mailboxes until each position has had a
chance to look at it?
 
thanks in advance
