When an asset reservation contains multiple items it would be nice to have the ability to check-in or check-out each items individually (or as a group). As it functions now a reservation must remain "checked out" until all items have been returned. This prevents new reservations from being made for items which may have been returned individually and are available for reservation. Asking users to create a reservation for each item individually may be a workaround, but it is less than ideal.
