I know this might be a long shot, but is it possible to set it up to only spawn things at specific coords, or spawn at one coord then travel to another before despawning to simulate shipping lanes?

I am in the process of hand crafting a large system and i'm trying to get it to simulate a "living world" kind of feel to it. I don't have any exp with modding or coding and my friend who usually handles that kind of thing is away while he moves to a new state. So I am in the dark here and really hope this is possible in some way.
