Maybe even go a step further:
When you're able to ID it visually (i.e. within icon range), make it IDable on the map too. For example, a friendly AC spots a formation of bombers, he tags it and hits a transmit ID button. That way the red dot, which shows up on DAR as a small rectangle, becomes , for example a cross. When you hover your mouse on it, you get the reading, for example "B26". As soon as the friendly AC gets out of Icon range, the dot disappears when out of DAR, if inside it returns back to the small rectangle we have.
Even if that was not implemented, I love the initial idea, it would make scouting missions actually useful!
