Apologies if this is in the wrong section, I couldn't see where else to put something like this. I am looking for this exact thing I think:
1. You also need the fancy product designer
2. Yes, you can.
3. Yes, you can.
4. Yes, you can.
no you can't. You need to do each design individually (or Copy and paste the products and just change the image)
Or you create one product and only change the image inside via the design module or multistep product configurator.
It depends on what you like to get exactly.
