Ability to read user defined properties from STEP file

The STEP specification (ISO-10303-21) has the ability to add user defined properties to model elements. It would be very helpful (actually critical for our use case) if those properties would be readable by Eyeshot.

#6051=PROPERTY_DEFINITION('MyUserDefiniedPoperty',$,#7);
#6052=DESCRIPTIVE_REPRESENTATION_ITEM('','f60a8e25-5578-4632-aad0-265dce4c59aa');
#6053=REPRESENTATION('MyUserDefiniedPoperty',(#6052),#6035);
#6054=PROPERTY_DEFINITION_REPRESENTATION(#6051,#6053);
#6055=GENERAL_PROPERTY('','MyUserDefiniedPoperty',$);

Many thanks in advance!
