Might be interesting to test. Make a straight line convoy down a line of longitude, and see what happens with the ships set to different AI levels.
It is possible to script zig zags though. Make the waypoints zig zag. Then select a few and loop them to the next waypoint after the zig with a % chance.
Ie: waypoints 0 to 1 goes due north, W2 45 degrees of that base heading to the east. W3 is 90 off the W1-W2 path (45 degress of base N heading West), but aligned due N of W1. Tell W1 to loop to W3 50% of the time. Now the convoy will go due north from W1 to W3 half the time I think. A major PITA to do for hundreds of merchant ships, but possible I guess. If the .mis files are text like Il-2, I guess you could copy a group of those waypoints in open water in a shipping lane, and offset all the waypoints by some number of nm with a little program and paste it into the next convoy/merchant instance and create a cloud of such paths...
