Formation Movement

[Scat]

Greetings and apologies if this is a question that's been "done and dusted" before... but...

Is there a mod that randomises aircraft movement to reflect normal variations in flight path and formation position? By this I'm referring to the way aircraft in IL-2 stay rock solid in their relative formation position, whereas there is always some positional variation in real world formation flying due to turbulence, pilot, etc.
