Purge with PVE options question

Sorry if I’m posting this in the wrong place. I admin a mostly PVE server, but am curious to how/if the Purge works with this. My intention is to have the server have a slightly more co-op feel to it (between players), without being overly easy.

My main question is if there’s a way to enable building damage from creatures/NPCs/Purge waves, but keep building damage by players turned off? If not, are there any plans to add further options like this?
