Frankly, I really don't know how to make that happen. I took a quick look at the function query stuff (I don't have them all memorized yet) and I just can't seem to make them bend that way.
I can imagine writing custom code to make it work but I don't really know how much effort would be involved. I suspect it would not be trivial. What I'd do is go back to the client and ask _them_ why it would be useful. Along with some estimate for figuring out what was necessary and let _them_ figure out whether it was worth it. Say a week's worth of effort to scope the work involved. From my viewpoint, given that the use of this feature is questionable at best, it's a service to the client to force them to lay out a clear use-case for this capability and also give them some kind of cost (in this case, just the cost to figure out _how_ to do it, not actually do it). Then they can make a rational decision whether the functionality is worth it. One outcome for them is to say "yes, our use case is compelling enough we're willing to pay you to figure out how to make it happen". Another outcome is for them to say "Oh, if it's not OOB functionality, it's not worth much effort". Yet a third response is "You're right, that makes no sense whatsoever, don't bother". Until and unless you give them the feedback that this is not OOB functionality, and get them to explain why they think it's valuable and let them know that it'll likely cost a significant amount, you're not giving them the information to make a rational decision. I've just seen way too many features implemented in various projects that wind up taking a lot of effort without being useful... There, rant finished.
