How to Display Heiarchy of Groups/Subgroups on the Groups Page

I do not believe this is a bug so I am submitting this as a support request.

I have created some groups and subgroups. For the life of me, I cannot seem to find how to get the Groups page to display the hierarchy of the groups, rather than just groupings. For instance, this is how they currently display:

However, I would like it to be like this:

Corporate
- Region 1
- District 1
- Store 1
- Store 2
- Store 5
- District 2
- Store 3
- Region 2
Training

and so on.

I have tried about everything I can find re: sorting and etc. Anyone know how I can accomplish this?

Thanks!
