I'm finding a lot of users uploading to the wrong subcategories because of the way the drop down box (after clicking upload) displays them.

I have categories/subcategories such as (example)

Cars
-fast
-slow
-business
Trucks
-fast
-slow
-business


The "Cars" and "Trucks" categories do not allow uploads, they are strictly for organization.

What happens is when a user goes to upload, the dropdown box only shows

fast
slow
business
fast
slow
business

with no reference to the main category they are in. Is there anything that can be done about this?

Thanks
