Quick Question on New Blog Templates

HI there, I was setting up new themes under the new blog templates extension. And I see how to edit the name of the theme, and put in my own description, support link, etc.

but I don't see where the over ride (or ability) to hide the "theme authors" URL, or name was located??

I have an all rights license, with re-branding allowed, so is there a way to over-ride that URL, or Author name from within the plugin?

Or do I have to go into the CSS file for each theme? I figured I could do that (if needed), but was hoping you plugin could over-ride the author name, so I didn't have to change each time, per update, per theme.

Thanks in advance.
