Cannot define Drag and Drop problems within a library

Hi everybody,
Is this impossible using Drag and Drop problems within libraries?
I’m on ironwood-master, trying to create a library with 300 problems of this type and randomly show a set of them to the course users for an exam.
But it’s not within the problem types list. I see the old deprecated version but not the v2.

I got this answer from @braden via Slack Ops Channel:

Drag and drop problems are not supported in libraries in ironwood ( and not even on more recent versions).
The new content libraries feature we are building should support any type of XBlock, but it’s still in development.

Thank you :+1:
