Hi
Unfortunately You are asking about building something new to the site
Template comes form a designer's mind and if His vision is to place it in a different way than developers who are making a template form a project doesn't interfere with it. But it's always being build from nothing, so a simple copy - paste will not work in every case. It has to be added, styled etc.
We are selling templates which should be treated as a tool for making a site. We do not make sites!
I've been hired many times to make for example a Photoslide's look from Sporter into Gamebox and noone has ever asked why the template doesn't have all Photoslides looks form every template's we've done.
