Can you do another color on the map for when you aren't sure what side they're on?
What do you mean by "you aren't sure"? Like, create a new minimap value (for example white) for certain units?
I guess it would be possible to code (by an actual coder, not a modder), but there are also other issues... Like the indicators in the lower right corner, soldiers stopping upon seeing a hostile unit, etc. So it would be a pretty complex change, and I doubt our coders would want to add this special case to the already long list of requests.
But hey, with this we could also have the Shrubinator.
(If you don't know what that is, don't ask...)
