is it possible to ajust zombie respawn distance?

[corruptbacon]

hello

to clarify what im mean,

example clearing as many zombies as possible in front/around a location or store so you can look around without an endless horde getting in the way, its works fine until you go a couple of buildings away come back to the same spot and all the zombies have re spawned

so is there a way to increase the distance before they re spawn, ideally i would like to be able clear large if not all of an area eg, sunset hills and actually have to leave before the respawn,

also would it be possible to stop or limit the zombies that crawl out of drains fallout of windows?

ajust quick time events to make them less tedious

any advice would be appreciated

thanks
