Choosing Lightroom Classic monitor for secondary full-screen display

I have three monitors attached to my system and I can't find a way to select which monitor will be used for my secondary Lightroom display.

When I had just two monitors, my secondary monitor was to the right of the primary and that worked out perfectly.

However, now that I've added a third monitor, Lightroom always uses the display on the left. I swapped the cables on the two monitors, rebooted, and Lightroom still uses the monitor on the left.

Is there a setting that tells Lightroom which monitor to use?  I searched these forums and the question comes up every few years, and the answer seems to be no.  I can't believe that Adobe hasn't yet added an option.  I'm hoping there is some secret option that controls this.

I did try to figure out how to trick Windows into renumbering the displays and that apparently isn't possible.  But since swapping the cables on the two outside monitors didn't make any difference to Lightroom, I'm wondering if it always wants to use the display to the left of the primary display.

And yes, I know I can exit full-screen mode on the secondary display and drag the secondary window window, but I really do prefer the full screen display.

Thanks!
