Organizing Templates

System

When creating a New Data Record, in the Create New Data Record window, say we have something like this

Category: Extranet Type: Customer
Category: Extranet Type: Supplier
Category: Extranet Type: Other
Category: Intranet Type: Finance
Category: Intranet Type: HR
Category: Intranet Type: Legal
Category: Internet Type: PressRelease
Category: Internet Type: Other
Category: Internet Type: Generic

I'm having about three templates in each category here. When I have about 10 or 15 templates in each category, the list grows very big. Is there a way to kind of folderize them, say three top level folders, one for Internet, one for Extranet & one for Intranet and clicking on them should provide the list of templates within them.

A note: I'm still on a older version of TeamSite, (4.5). So, I don't know if anything has changed in 5.0 or 5.5.

Any help is appreciated.

Thanks
