its really 63 different combinations for FTL stuff. But i have no idea about limitations. Thank you for your suggesting. Its already really confusing for me with isboxer's default settings. What i want is that im gonna press Alt + F, then all characters follow that character. Thats it.This is hard to setup?

It failed, so i tried EMA's follow. My characters are all different realms. So im phasing alot ( english,german,spanish,french realms). Consider a team 2x english, 2x italian, 2x french, 2x spanish realm characters. When im questing (2x4 group), i hit EMA follow keybind. Some of them following, some of them are not. If i regroup all of them ( 8 of them are in same group), EMA follow is working. This situations make me crazy
