Create custom image from currently synced image

Could we please add a button to be able to create a custom image from the currently synced image?
This would allow people to keep an image that they’re using with a specific kernel to be used whilst still getting updated images.

Use case being that you have a selection of servers all running the same kernel and that kernel needs to be the same throughout due to other dependencies (OFED for instance).

We’ve had to turn off image syncing as we need to keep the same kernel which means that I cannot test/sync the newer Jammy release and having to create a custom image each time is not just a long process but also seems to be a little flaky (going through this on a support request currently).
