Allows users to update availability once a game has been accepted on that day
Once you have games scheduled for a day, you can no longer update availability. Say you do not want any more games that day, you would block off the rest of that day, but this is not possible with the current system, thus showing as available when you no longer want to work any more that day.
This feature already exists. It is controlled by your scheduler. Your scheduler has the option whether or not your availability is locked after scheduling or not. I would suggest contacting them regarding their preferences as we do already have the option you suggested, but the availability locking feature seems to be turned ON by your scheduler. If they desire, they can turn this feature off would would return to the functionality you are looking for. Hope that helps.
