Bug 15524 added the ability to set maximum numbers of holds per patron category in the circulation rules by library. However, there is not a way to limit MaxReserves by patron category regardless of library. This causes difficulty if ReservesControlBranch is set to the item's home library, potentially allowing for up to the library's hold limit from multiple locations. MaxReserves can stop patrons in large consortiums from having very high numbers of holds, but it doesn't allow that limit to be changed based on patron category.
Our consortium definitely needs this!
