Live View Buttons & Links Open Cart (Vqmod XML) or Module

Hello to all Open Cart Developers. I would like a module/vQmod xml made up which when i create a product on open cart it has a section where I could have a button on product page call live view and admin I have attached a module which is sorter the way I am after but needs a few changes. Rather than creating a database and installing open cart to be able to get a http:// link for each theme. I would like some how to be able to put in a link example [login to view URL] and it is able to read the link. That way it would save me creating an installing open cart over and over again. Currently the module I have at the moment can only read standard [login to view URL] You can see button demo on this product page [login to view URL]
