This has no practical MA use but would be a great scenario/event tool, similar to allowing CV hardness changes and whatnot.
In the dar flags, add a new mode "Bomber only?" -- so that any dar, be it range, dar, dot, whatever, only shows up if the target is a formation-capable plane (defined as: Boston III, Ju88, Lancaster, B17, B24, B26, B25 (if formations enabled), Ki67, Ar234). Let's throw in C-47 just in case the scenario/event calls for it.
If toggled it does not display fighters, only the above craft.
Like I said, NO ma use at all, but it would give CMs a lot of choices with how they want to do things.
