On the subject, I wrote a patch to allow this specific feature several months ago, but it was rejected by Vladimir because it lacked some features the maintainers deemed desirable. Depending on your specific needs, it may suffice; I would be happy to send the patch to you. It should work on the latest GRUB 2.02 beta.

I am considering re-implementing this feature with a new patch, but have not had the time. I would be happy to resume work if anyone is interested.
