Datasmith collision boxes issue

Greetings,
I am using 3dsmax for modeling and making custom collision boxes for use in UE4.
So far, the usual naming convention for collision boxes ( UCX_ObjectName_001 ) worked like a charm when using FBX export method.
But, when i export something to UE4 using Datasmith, that naming convention doesn’t work anymore.
Problem is, when i try to use multiple collision boxes for the same object ( example: UCX_wall_right_001, UCX_wall_right_002 etc. ) only the collision box without _00x suffix will work ( UCX_wall_right ), the rest are ignored.
My question is, is there a way to use multiple collision boxes for the same object using Datasmith?
Thank you.
