Rise | Confirmation of solution by supervisor

Hi Jens, 

Thanks for reaching out!

How about adding a Fill in the blank Knowledge Check block which will accept a confirmation code that only a supervisor can provide? 

This way, they'll need the approval of your supervisor as well as the code that they will be providing in order to proceed with the course. 

I'll also open the floor to other members of the community in case they have other solutions that they'd be willing to share!
