I see this was replied to in the Facebook group. I will copy and paste it here for reference:

“No, they won’t do that.
They are basically just normal SPA single player templates and run exactly the same. It adds one image to each composite. The difference is that the smart object is duplicated multiple times. So when it adds the image to the template, the linked duplicated smart objects are also populated.
If you are wanting to make a template like that which put different images on it, then it could be done through EZ Composites. However, the template design would be somewhat complicated if you don’t have a deep understanding of how EZ Composites layers work. For EZ Composites, I really only have training for using the layout designer. I purposely never put out any training for going off-road and making templates manually because it gets complicated quickly and is just too much to expect people to do on their own. With that said…. it can be done if you have the photoshop knowledge and the EZ Composites layer structure knowledge to pull it off.”
