Jetway with fixed leg build and test in editor mode

Hi I’m in a process to create a fixed leg jetway but it gives me a hard time.
My first idea, if possible please create a sample for a fixed leg jetway.
Second idea is the testing/finetuning and the trial-and-error of the model in
the editor itself. Currently in the editor mode I cannot test the model, only
place it. It is not possible to move the aircraft in slew mode while in editor
either. I need to build the package, copy it into the community folder,
restart the sim, test it. If I need to change someting I need to delete the
community package, open the editor, re-export the model, build the package,
copy the package to community again. In the package the SimObject seems to
remain in GLTF format, I tried to overwrite that GLTF with a new one directly
in the community package to save the steps above but if I do this the jetway
disappears, I need to rebuild the package anyway. The fixed leg jetway are
different fromt the conventional jetway that the “telescope” (hydraolic part
that lifts the ramp) is not pitching with the ramp together, it remains
perpendicular to the ground.
