Adding more custom product pages to /store/ directory

[emresavas]

Hello,

I want to create more custom product pages as default templates in store/ directory. For example for web hosting services I want to create /store/web-hosting/index.tpl and use it in with a product group page (gid). I tried to find how Whmcs set these custom store pages for spmexperts, codegouard etc but I couldn't find.

Someone advice me an efficient way to assign custom templatefile to a gid?

Thanks.
