Referee and Umpire Shift Confirmation Emails / Reports

When a referee is assigned to a match an email will be sent out reminding them of the upcoming games they have been scheduled for a day, as per the settings selected in the referee schedule config area. However there is no way to know if the referee is available for this work shift or not unless the referee on their own accord contacts you and says they are unavailable when they receive the reminder email. A system like how team captains/organizers receive availability confirmations from their players after the game reminder emails have been sent would work perfectly in this situation. If referees could be sent their game reminder emails that included a 'confirmation of availability' link it would help admin organizers know and check if a referee was confirmed for the shift they have been assigned. It would be great as well if in the calendar this would show up as a "Warning" or a "Clash" error for the fixture alerting to the fact that the referee is unavailable.

This would stop situations when referees do not show up for shifts because they had prior engagements or simply did not get a reminder email. This is especially important when there are over a dozen referees scheduled on a night as you would then be only need to contact the referees that have not confirmed their availability as yes or no rather then constantly having to keep ask referees by other means.
