User interface - Grouping Collection Types

I have an important question regarding ways to group the collection types in the left column (Collection types navigation panel - the look is the same both for the Content Manager and Content-type Builder).

We’ve got 50+ Collection Types in our system and some of them are dedicated to totally different type of action/ user. It would be extremely helpful to have them grouped the same way as the Components (in the Content-type Builder) are - so the Title of the group and then a dropdown list with all elements.

Is it possible to do so?
I really do hope it is! This unordered list has been a drag for our Customer so far…
