Two problems with this, it redeploys to machines that already have the software part of that configuration reinstalled (which is disruptive to people) and it is a very time consuming.

Maybe there is a better way to do what we are doing, when we image a new machine it goes to a staging shelf that is on and always getting updates etc.  When a new machine is needed or a user has a problem with there machine (be it virus whatnot), we get a machine from our staging shelf, add it to groups in Active Directory for what Software is needed  and licenesed for (based on machine function, and department it is going to, Like office, or Adobe Creative suite, or Security Camera Software, etc.)  we want to have that be able.
