Custom Rating - DUPR Waiver

We have a waiver program for rating exceptions that uses the MyDUPRCoach process. If the player doesn't have a DUPR rating, then this is not an issue as the coach assigned DUPR gets added to their DUPR profile and that allows players to sign up for whatever events they want to. If the player does have a DUPR rating, then we need to create a custom rating range/value for them and edit events to allow that custom rating range/value. It would be convenient to create a custom rating where it is a number that can be used with the DUPR rating restrictions to allow players to be allowed to sign up for events. 

Bonus would be to create a period that after which would nullify the waiver so that we can do a re-evaluation of the player.

Scenario I have the issue for: I have a player who has a DUPR rating of 3.000. Our next DUPR range is 3.250-3.749 and this player believes they should be allowed to take instruction within that level for whatever reason. If the waiver process says that this player is in fact a 3.259, it would be nice to input that value into a field and have it be automatically used by rating restrictions rather than having to do something with a non-number string in a custom rating. Then after 6 months - this player gets an alert that they need to have another waiver evaluation to ensure they are still playing/competing at that level.
