Ability to mark too-late unregistration as 'valid reason'
One-sentence description
The ability to mark too-late unregistration as 'valid reason'
Motivation
Currently there is a separate sheet where we register the fines for absence at activities or unregistering after the deadline. Sometimes people have a valid reason for this. It would be nice to mark this on the website as well, so a separate administration is unnecessary.
Desired functionality
For people that unregistered too late or were not present during an activity, it should be able to mark their absence as 'valid reason'.
Suggested implementation
A checkbox or something?
To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
