I really dislike GSX’s marshal for arrival guidance but the default MSFS 2024 ones are fine…they’re just not at the gate/ramp where BATC directs me to park and I def prefer following what BATC directs and so the only thing missing when I get to that parking spot is the arrival aircraft marshal. I noticed some effort made to integrate with GSX, so I thought perhaps you might consider seeing if you can tap into the default marshals to have them appear after BATC decides what parking spot I’m directed to. I would love to have this option! Cheers and thanks!

That is not possible, the MSFS marshal is linked to the use of the default ATC and there is no access via the API for developers to trigger it manually. That would require an update from Asobo
