[Closed] [MXS] Check FBX file units on import?

Hey people, long time no see.
I have an issue while importing and exporting fbx files with different unit systems.
Would you know if there is a way in maxscript to check the unit system of an incoming fbx file, to set max unit system accordingly.
I tried to mess with rescale but it seems buggy af.
So if the incoming file is in cm, i’d like to stay in cm all along.
Thanks !
