IPS MC 2.2 (releasing soon) will support auto updating of sensors.The sensors do have an auto update feature that is not supported by IPS MC (you have to use IDM or CLI).If you manage your sensors via VMS, then I recommend waiting for IPS MC 2.2.
All dev and test resources are fully committed to the 2.2 release (3 weeks to FCS). This particular issue is currently being worked on. IMO, a patch would take at least 2 weeks if the resources were available. So I would recommend waiting for 2.2.
