macOS VM Image/prepare for transfer on m-chip

Hi there,
I am trying to share a macos 15 VM image across multiple machines for cicd nodes, but there is no way to create a VM image from a VM/.macvm file?
The documentation refers to a button called "prepare for transfer", which does not appear when I right-click on the VM in parallels control center.

So far I have zipped and scp'ed the .macvms themselves between my hosts. This is infinitely more clunky than competitors like orka-desktop, which allow pushing images in OCI format to registries.
Is this feature no longer supported in parallels desktop 20 or am I missing something?
Is there another way to move images between hosts?
