A script to make released monsters walk away from transitions over time

[Eraamion]

It seems to be a problem with both released undead and released blood golems to eventually end up camping at transitions. Unlike the players, they do not tire of it and stay there with potentially unavoidable and lethal consequences for the young and unexperienced. Is it possible to script for these specific monster instances a walking-away behavior please so that they would always distance themselves eventually, giving the players a chance to react, even if only to flee?
