Stairs to ifc

[m.kopaniaAQZ65]

Is it possible to export to IFC only structural part of the precast (or any other) stairs?

Because, even when I turn off in 3d view treads and risers and check export only elements visible in current view during the export, it exports also this finishing layers to ifc.

...only the Structural Part of the Stairs? How do you define a Stair component as "Structural"?  What about overlapping to Stair Types to create one Stair Type? One Stair Type is the Supports. and the other is the Treads and Risers?   Then remove the Treads and Riser Type for IFC Export.
