Is there an easy way for me to move this project back from 'test' to 'prep' in CM Synergy 6.4

We have a few shared projects used as buckets for adhoc pieces of code, and it looks like one of them was checked in 3 weeks ago; they normally sit at 'shared' status, but one has now changed to 'test' status and build managers are now unable to add new objects (permission denied to workarea folder).

Is there an easy way for me to move this project back from 'test' to 'prep' that anyone knows?

Thanks in advance

Mike
