Would it be possible to have a 1.3 beta branch on steam?

I think it's accepted that a significant portion of the players are playing Rimworld modded.

The regular 1.3 updates are great, but sometimes mods need a bit of time to catch up with the changes, which means for some of us it's either changing how we play the game after each update, or wait a week or two until it becomes playable with our favorite mods again.

It would be a great QoL option, to have a 1.3 beta branch available on steam, so we can choose to upgrade our version, when our mods became stable for it.
