... we have many students and many things we award stamps for, so it's
quite cumbersome to only be able to give a stamp to one student at a time.

Is it possible to have a kind of "quick add" feature where you check a
checkbox behind each student to be awarded a stamp, enter a generic comment to
be added to all of them, and a button that then gives this same stamp to all
checked students?

That would save us a lot of time and effort!
