It would be useful if the availability of a particular element could be limited on a service-by-service basis when the services are performed by more than one factor. In this case, other services and other elements would normally be available for booking, but for a particular service it could be determined when that element is available.

Currently, the availability of services can be limited by the use of rooms or equipment. Similar functionality would also be useful for managing factor availability in order to determine factor-specific time constraints.
