Wanted to also +1 this, as I was flying the Mirage other night I had the same thought process. A factory, or bridge, power plant, etc. One object or a few, but not near as many as A/G ones. Think this would be a great addition to aircraft that aren't dedicated CAS.
Also, to note the order of A/G missions, is Hard than Easy first on the F10 list. Nothing big just my OCD noticing :)
