Membership Discounts - Daily Free Hours

Right now there is a systematic limitation for the free discount hours for memberships. The limitation is that it must be a full/round hour, I.e. 1,2,3, etc, and it does not allow for .5 hour increments. I have had multiple customers request 1.5 hours free included in the membership, as it is the standard in my area, but I am limited by what I can offer and feel I can't compete with the competition. Due to this, I have had to build a lengthy workaround with some shortcomings to allow 90 minutes of free play. It would be great to see a change allowing the free hour increments under membership discounts to include .5 hour increments. The system can already schedule in .5 hour increments, so it feels as though this should be a fairly easy adjustment.
