@v1ld I did go back today and tried the long-press A function you mentioned, and it does work, though it could use some improvement -- namely I still have a hard time discerning which containers I have already looked-thru.

And yes, the long list to scroll thru when trying to manually assign radial slots is a real nuisance. Even at 1920x1080 there should still be plenty of screen real estate to list more than the current narrow box with it's loooong vertical scrollbar.
