I'm hoping there is a way to group my question banks into categories, but I haven't found it.

For example, I created the following banks:

I really like the ability to use Groups to pull a certain number of questions from each bank. This ensures that students will receive a similar number of questions in each group, but not every test will be the same.

But when I add a Question Group, I end up with way too many Banks to pull from:

Does anyone know if it is possible to create categories for Question Banks? Or, is there a "vote for this" request for this somewhere?

Thanks!
