This idea has been developed and deployed to Canvas
For on paper or no submission assignments, if a grade is flagged as missing, but then later points are added to the gradebook, the missing flag remains. The instructor then needs to manually remove the missing flag, even though points were assigned. It would be great to have the missing flag automatically disappear once points were entered (signifying that it is no longer missing). The option to have the missing automatically turn into late would be even better.
