Adding Marketpress Product to GT3 Page Builder Featured Post

Hello everyone.

Sorry for the long title but currently I am using a theme that has a GT3 Page Builder built inside it. There is one drag and drop feature called "Featured Posts" and there are options for Post, Portfolio and Page.

I am terribly bad at coding but by the looks of it, it doesn't look so hard to add in another option for Products. Is there anyone that has been playing around with GT3 page builder and added this feature?

Thank you very much in advance
