Android Beta - allow certain worlds to not get BETA version.

I know we’re still waiting for Minecraft Preview to come to Android, but we already have Minecraft Beta that you can sign up for.

The problem with Beta is that it applies Beta to EVERY world we create. Would it be possible to add a toggle? Whereby you can decide whether the world you’re creating (or the existing world) receives the beta version or the stable version. This would allow us to play in a beta world and enjoy new features and blocks, but not jeopardise our long-term worlds getting a beta version. I have played with Beta before, but it’s not good for long-term worlds.

I hope MC Preview will be available on Android one day soon.
Thanks
