Doorknobs for interior double french doors

I installed double french doors to the master bedroom and haven't yet cut out the doorknob holes. Actually, I haven't fount what I wish to install. Theses are solid double wood doors, 1-3/8" thick.
Here's what I would like to do: Get privacy doorknobs that latch to the head jamb instead of the side jambs. This way, they can latch independently of on another. I do not want to get an exterior-type bolt that locks the bottom and top on one door, and uses a standard lock and handle on the other door. I envision the convenience of opening or closing both doors simultaneously and quickly, but also locking them independently. I prefer to avoid a sliding bolt screwed to the outside.
I don't mind routering a slot in the side of the door to install the mechanism.
Does something like this exist? I haven't found one yet. Where can I buy them, and what would this arrangement be called?

Why not just install button locks on the top of each door. That way, you can install dummy knobs and the doors will open with just a pull, alleviating the need for a through hole.

I haven't found button locks that install to the door but aren't part of the door handle. Any brands you can suggest?

I think what Larry is talking about is a ball catch. This is mounted in a hole at the top of the door with the 'keeper' in the top jamb piece. This is not a lock per se, but it will keep the door closed.

FYI - The ball catch I refer to is often found on sideboards on the doors at each end. These are the small ones. They are available in larger sizes. See link below.

The piece on the left goes in the top of the door - the other piece goes on the jamb. These are available up to at least 7/8" in diameter. The ball has a spring below it - the tension is adjustable so you can make the door as easy (or as hard) to open as you want.

ball catch

Good suggestion on the ball catch. I bought a set, to create a detent action upon closing. This method will also be used on the closets, which are also double doors. Occasionally, it will be necessary to lock the bedroom doors, however, and the ball catch is not capable of that purpose.
I only know of sliding bolt locks that can be used to lock the top edge of the door. I wasn't planning to use that type, but rather something that has more of a built-in appearance, or is hidden like the ball catch.
