PR: Can't overwrite *_Common.LoadBearing with a user defined parameter

[MIVillegas]

Problem Description

... Hello.
I know not all the families have the "Loadbearing" instance built in parameter.
Therefore we have had to implement an office-wide ARC-Loadbearing parameter which we also prefer to use as type parameter.
The problem is that when we use this parameter and export the IFC with a "supposedly" correct mapping file, the corresponding *common.LoadBearing parameter in the exported IFC does not react and takes only the value from the "Loadbearing" built in parameter.

Is there a way to overwrite it?
I think the translator works because, for test purposes, I assigned the ARC_Tragwerk (loadbearing in german) to other common parameters, and it worked.

Is perhaps my syntax wrong, or is it actually impossible?

Pset_WallCommon	LoadBearing	ARC_Tragwerk
Pset_WallCommon	Combustible	ARC_Tragwerk
Pset_WallCommon	IsExternal	ARC_Tragwerk
Pset_WallCommon	Reference	ARC_Tragwerk

Thanks in advance!
