I remember seeing the pic too. I was thinking it is something I could do. My bars are secured to the spring hangers with a pin. That pin should be plenty enough to hold the bars in place when not attached to the hitch. My bars are tapered, so I could just slide the bar up in the hanger until the pin was snug enough to hold them there. This would work with any of the Equal-i-zer type WDH/sway control hitches.
All that being said, I usually remove and store the hitch and bars in my front pass-thru storage during setup. If I'm only unhooking for a short time for some reason, I've been known to lay them across the A-Frame behind the tanks. They are not readily visible, and are easy to access.
