I created a custom element for Shogun .. That should allow for the usage of the current CE code for add to bag.
Was easy to create a basic one, but we do need a little more logic, and the ability to select the product and not have to find the ID (ex: a product selector)
It does look to be working but it is a little slow , Give it a try .. remember it is a little slow. The bubble chain is large ..%Ooo..
