Testing Multiplayer with Level Streaming + LevelTransform

I have a map in which I dynamically load levels and place them with LevelTransform.SetTranslation. There is a known issue where play-in-editor does not handle the translation correctly. So I’ve been testing single player by launching the game, which works as it should.

I also need to test the multiplayer functions. However, I can’t just select the number of players and play in editor because then the level transform doesn’t work. And I can’t seem to find a way to launch for multiplayer in the project launcher.

Any advice on how to test my game in multiplayer without PIE?
