Nope, what you are looking for at the moment do not exist haha, it is also what I’m looking for. With a bit of time you will get use to the cutout, at least for me it is totally worth it, case is amazing other than that. Alex Goldfinch has said on Reddit they are working on a CC Button case, and those who have bought their cutout case will have a 20% exclusive discount, so we will have to wait to have a top quality open bottom leather case with cc button, at least has been worth it to buy to cutout case.
As far as I know RL are not introducing Cc button in their Open Bottom case.
