Prochannel "icons"

When adding a module into the Prochannel for a track/bus, clicking the "+" sign brings up the list of installed Prochannel modules.  Some of them have icons on the right side of the list that show the module's appearance, some of them don't.  Going from memory, but it seems that many of the ones without an icon used to have one.  Is there a way to get icons to show for each module?  (I find the quick visualization helpful when I'm looking for a specific module, sometimes I can remember what it looks like better than I can recall it by name.)

You will lose any custom menu set ups, IIRC.

That restored most of them, although not all.
Thanks!
