M1 Mac, macOS Ventura on an external drive?

Hello,

I'm interested to know peoples experiences here. I've got an M1 Mac and I'd love to install the Ventura beta on an external drive. Is this possible? Has anybody had any luck?

I haven't looked into this issue since the Monterey betas. Apple decision to make installing OS releases on external drives difficult really hampers developers ability to test. Has anything been resolved/improved?

Cheers, Ross.
