Is there a way to limit how many times an individual user can submit a particular catalog item? For example, if I have a quota of 10 machines on a catalog item, I don't want one user to request the same catalog item 10 times, thus preventing anyone else from requesting the item because of the quota limit.
What I am looking for is only allow the user to request one catalog item at a time. If they hit submit again on the same item, before the first request expires, the new request should get denied. If a second catalog item is present, but not yet requested, this second one can still be requested, even if the first item is still active. Is there a setting somewhere, or do I need to look into a custom workflow?
