We maintain service/support contracts with third party vendors. For example, we purchase support in 25 hour block increments from a vendor for maintenance, service and repair of our smart boards.Since active period is required for creating contracts but not necessarily relevant for this type of contract I would rather have something like active hours instead. How would you recommend creating this contract? If it's not possible, could I have it added as a feature to add in a future release? I would like to be able to track hours purchased and to be able to deduct hours when used.
