Product combos listings

Hello, has anyone ever created an Amazon listing for a product/ combo of products ? If so, is it easy?
Just to confirm, I’m not talking about private label, I’m talking about a product combo that currently dosnt exist on Amazon. Thanks

It can be done I’ve seen someone do it on YouTube but not sure how brands would feel about it people

Do it with lego minifigures add little bits to them makes it harder for me to jump on the listing
