Increase deer return time?

I think pushing deer is fun but if the game is a bit laggy (and in aoe2:DE if YOU are a bit laggy and not just someone in the game is laggy) then pushing deer becomes almost impossible. The timing is so close that if there is a hint of lag its almost impossible even if you are not macroing and ONLY focusing on pushing the deer. Could we increase the "deer return time" by about 1 second?

edit: im talking about the time a deer will stand still when it has been pushed out of its starting area before it decides to return home.
