distributed grading (Support #760)

Dear all,

I just learned about AMC, which looks like a really nice tool to generate exams!
So far, I haven't used a lot of multiple-choice questions, but I would like to be
able to grade electronically, in a distributed fashion (corona...).

Does AMC provide any support for distributed grading, or do you know of any
other tools that may help? For example, there should be some locking mechanism
that ensures that no two graders grade the same student solution.
Graders should be supported in grading a single task of the exam. For example,
they may want to exchange information about how to deal with specific student errors etc.

Is AMC simply not designed for such a task because AMC assumes that all open questions
are graded before scanning?
