That's exactly what I use the wonderful Mission Editor for. It takes some work (I chalk it up to pre-flight briefing), but my flights take off and circle the field while climbing to altitude. Then it's off to the mission and back. The other thing I use if for is to reset my German FFA's parameters. The home field assigned to FFA 13 has nothing to do with the actual fields they operated from, so I rewrite the entire mission. If I could overwrite the entire instruction set and have it automatically do what I want...well, I can't, so I do each mission by hand and call it good.
