Can a program be installed under a subfolder? /Programs/subfolder/YourProgram/

I’d like to install programs/packages under the same subfolder, is that possible?
Meta Recipe is an invalid solution here, as it places multiple
programs content under same Program and not a program under a Subfolder.

I tried this but is seems to not do anything

Meta recipes are no longer supported (actually, I hope we have updated the documentation to reflect that). Anyhow, there is no support for installing programs as subdirectories of another entry from /Programs.

Perhaps what you can do is to have an extra directory tree such as /Groups/Name which is basically an aggregation of symlinks (or bind-mounts) to entries on /Programs.
