I have been working on some multiplayer code for a while now, and I find myself constantly going through this process:
1) Hit the run button and enter in all the host command-line parameters
2) Wait a couple seconds for host to start
3) Hit the run button and enter in all the client command-line parameters

This doesn't seem like a big deal at first, but I like to test my changes every few minutes sometimes, and this really hurts my productivity. Is there some sneaky way to start up a host and client(s) with a single button press? This would really speed up my testing.
