Merging Custom Templates with ............

[PixelFx]

Can someone please post a custom walk through of how to Merge/mofe Custom Templates into default group templates listings?

or at least have them group in the same sections aka,

if I make a new postbit_template, how do I get it to group under the postbit template directory rather than at the top of the page. After adding over 30 custom templates to the site, it would be nice to group stuff better.

thanks
