Help With Multiplayer Quaestion (Creating Teams)?

so recently me and a couple friends have started a part time project just to experiment what we can do with ue4 and im wondering if there is anyway to make a team system in a multiplayer game? Thanks for any help and if you need or want any information that will help then just ask but at the moment the project is very bare bones. this is also on the most recent version of ue4 4.14 i think?
