Episode Track/Galactic Challenges

Do we know if there will be anymore galactic challenges for this episode pass? I got the "complete 5 galactic challenges" episode quest but see no evidence of an upcoming galactic challenge to complete the quest. I'd really like to get that nightsister LST in pursuit of the secrets and shadows assault battle team, but I'm having a hard time seeing how that will be possible without getting the 10K episode points from that challenge and the chapter completion bonus.
