Separate Audio from one switcher is it possible??????

Hey There Right now we currently have to use 2 separate switchers to send out our 2 different shows that use the same cameras which is fine for now, but we want to upgrade into the 4k market since we are shooting everything in 4k and want the raw footage in 4k, as a result, we need to buy a new switcher and I was wondering if there is a switcher that can send specific audio to specific outs on a BMD Switcher or if no matter what I would have to get 2 separate switches one for each show?

The only workaround I was thinking about is using a video hub to either split the camera feeds or use it as a second switcher and send audio through the individual sdi Line.
