so could i make a red team spawn in one place for slayer but in another place for CTF? how would i do that?
Make them gametype specific. But forge on the gametype mode you want the spawns on. eg: CTF spawns go on gametype in the forge lobby go to CTF and then make those spawns gametype specific.
Go to the forge lobby. Select a gametype other than basic editing (CTF or slayer) Play forge. Place an initial spawn where you want it in the gametype you selected. Press [X] and go to "Advanced" then change the label to CTF, slayer, or whatever gametype you want the object to spawn exclusively in. In the same menu change "Gametype Specific" to True. Repeat for each gametype you want to be playable.
