Are you willing to submit a PR?
I think this will be best handled internally like the typical Xcode deployment pattern, but happy to contribute. Opening this as requested in #1133.
@maxim-lobanov opened per your request. Thanks again!
@markavitale , Btw, I have found the following on Apple site:

Does it mean that both Xcode 12 for macOS Universal Apps and Xcode 12 will be merged in next beta?

Probably not for beta 2, but yes, Xcode 12 beta 3 should be one single release with support for all Apple platforms and architctures.
@maxim-lobanov FYI Xcode 12 beta 2 has now been released (for both the standard Xcode 12 Beta and the Xcode 12 Beta for macOS Universal Apps). Ideally when this is deployed, it will be with build 12A8161k.
@markavitale we're going to deploy VM image with Xcode 12 Beta 2 next week.
Just to clarify, we are going to deploy VM image with Xcode Beta 2 (12A6163b) next week.
We didn't start adding Xcode 12 Beta for macOS Universal Apps yet. We still have some concerns about adding it to images considering the fact that next betas will be merged to the single product. Every Xcode version is pretty huge and significantly increases image-generation / image-deployment time. We will let you know as soon as we have updates on it
Hello @markavitale , the good news.
Apple just released Xcode 12 beta 3 and they merged both Xcode versions to the single release:

Any Plans to support Beta 4 soon?
It is currently not possible to upload Builds made with beta 3 to Appstore Connect using beta <=3.
