[RE-wrenches] Awkward Mid-clamps & jigs for installing or, removing modules?

I made a pair of jigs out of some two foot lengths of 20-80 (That 1" square aluminum extrusion with bolt slots on each side) and some unequal-leg angle. I cut some 1" long pieces of 3"x 6" and 2" x 3" aluminum angle, two each. Then I drilled the short legs and bolted a long and a short angle to one side of each piece of 80-20.

To suspend a module I adjust the distance between the two angles, tighten them down, slide the jigs (short angle first) flat up under the bottom rail, and tip them up 90 degrees. The short angles hook on the rail and the module can rest on the long angles. I can adjust them for any module and it's a lot easier to get the array aligned.

Single-handed mounting for replacing or installing modules on racks. My
helper installing an array on an Iron Ridge rack commented (like so many of
you have surely thought) that the mid-clamps are really clumsy. His
suggestion was that on his, he would lengthen the rail and only use end
clamps so each module would be independently mounted, removed or the Enphase
replaced. Of course this would apply to UniRack and other mid-clamps too.
Can anyone recommend a jig for supporting the line of modules, while they
are individually being clamped or unclamped? Perhaps a long length of Al
angle braced back to the rail, so the bottoms of the modules can sit in a
straight line while they are being clamped. Even a couple sliding Z-shaped
spring hooks that can support the bottoms might work one module at a time as
long as the rail is s
