Rubric as Favorite

I have a rubric that I use for bookwork and questions. How can I set this to be a favorite column so that I can add it multiple times at once?

Hello,
In the current version 7.0.23, a Rubric can't be added as a favorite.
That option will be included in our next version though. If you'd like to give it a try before the official release send me a message from the app (help > support&Suggestions) and I'll send you a Beta version
