I am using the Premmerce plugin to change my product URL’s to just show the “Primary” category.

In this example I have set the “Hot Water Boiler Accessories’ category to use the Single Product Page template called “Product: Generic”.

However it is not showing because I have set the ‘Primary Category’ for that product to be “Hot Water Boilers”.

Is there a way your plugin can recognise that the product should be using the “Accessories” Single Product Page template rather that the “Hot Water Boilers Template”?

Hard to explain. I can give you login details if needed.
