Multiplayer Human Player Reload/Invite

Hello, Is there a way to invite someone back into.a multiplayer game after saving and reloading it? I am able reload the game; but still not seeing a way to bring other human players back into it. This has been and remains one of my.main issues with AOE 3 DE; since a friend and I are trying to play online or LAN; but usually have to leave before the round is done (typically hard difficulty 3*3).
