If it is intended to submit solutions for an exercise sheet via an external system # (e.g. on paper), then the course participants can generate a pseudonym on the page # of an exercise sheet.
An external submission that carries this pseudonym can then enable correctors to create # submissions in Uni2work that correspond with the external submission.
This way, feedback and bonus points can be managed directly in Uni2work, even though # the actual submissions are done externally.
