After attempting to make some custom HARM missiles and an HTS pod, it has come to my attention that there is currently no way to extend a vehicle's marking range or sensor array(neither magazine nor weapons based). The only way to increase the range is to manually override the base vehicles configs.

I'm proposing a feature addition such that vehicles gather targets not only from their own sensors, but also from the sensors on equipped vehicle magazines;
For example, an HTS pod can be defined as a vehicle magazine, and have it's own long range anti-radiation sensor. The vehicle would then be using this new sensor alongside its existing ones. This will also keep from having conflicts with missiles as most have their own sensors in the ammo.
