Need Help With Custom Spawns

[Left 4 Shred]

I'm running my first server and have run into a snag. I've been able to find solutions for most of my problems through googling until now. I'm trying to add a few custom spawn points to my server and am at a complete loss. I ran through Louisville claiming and releasing various houses as safehouses to record their coordinates. I have seven locations I'd use as spawn points for a custom spawn region in Louisville. Most of what I've found is for setting a single static spawn point and everything else has left me very confused. I'd like to set it up so that clicking on Louisville would send the player to one of the seven spots I picked out while retaining all the vanilla spawns from other regions. I have no idea what I'm doing with this. 

 

If anyone could help me figure this out or point me to a more concise guide on this specific thing I'd really appreciate it.

you need to modify the spawnlocations.lua + spawnregions.lua files

also theres a mod that achieves this that you can download on the steam workshop
