Need Help Delaying Spawn Rate

Game Modding | Call of Duty: Black Ops 3 | Scripting

SGT.FUNNYMAN:

Hey so I recently added in Nova crawlers into my map off a old Harry Bo21 file and they work, however I have a issue where they spawn non stop in the round leaving only a few actual zombies per round. Is there any way to delay/limit the spawner? This isn't urgent but would be a nice quality of life improvement. I'm not sure the on the scripting considering its not a normal zombie spawner but and suggestions would be appreciated.

TLDR: Limit spawn point to spawn like 5 to 10 zombie's per round
