SPPB integration seems pretty cool, however the layout capabilities are limited?!

As far as I understood, the layout design is limited to 1 common products list and 1 common single product, right? Sorry, but I think this is a real show-stopper for the pagebuilder feature and surprising restriction. A shop might consist of total different product categories, like tangible stuff, digital items or even services. All those might exist on the same website. They might need a total different presentation. A different layout and style. Frankly, I did expect to create multiple layouts and designs. Maybe based on a category, or maybe a certain shop menuitem...

I am just writing from my demo experience and from reading the documentation.

PS: Really would like to hear other users and their opinion.
