Well there are 2 ways that i know of...1 is with a script, which seems like alot of work...the other is a little easier.
1. Copy the marker called "Respawn_Guerrila".
2. Paste the marker, now named "Respawn_Guerrila_1".
3. You are finished.
You can paste as many as you need...and they will randomly spawn at all locations.
