Lots of missing airports and strips.

Is there a way to add all the airports that are used in FSEconomy to MFS? Too many are missing, most of the military ones and they aren't even small, some others are named differently, sometimes there's just a control tower in the sim with a grass field, sometimes the airport's satellite image is correct even if blurry, but I'd like to be able to get there by gps instead of guesstimating the position by looking at google maps and the ingame vfr map.
