Weldment Profiles from design table - Custom Properties vs Configuration Specific

I have a sketch of a steel section, that is driven by a Design-Table.

I also have a macro that takes each configuration and saves it as a weldment profile (.sldlfp).

This works well for creating a heap of weldment profiles for particular projects.

The problem is that the Design-Table drives Configuration-Specific custom-properties, so when I create a structural-member the cut-list does not have any of the custom-properties.

-----------------------

I tried using \$PRP:"custom-property-name" to link the custom-properties to the configuration-specific properties.

But that fails because when used in a structural-member, it inserts the FORMULA, not the RESULT.

--------------------------

So we are opening each file individually, and using copy - paste to transfer the values from the configuration-specific custom-properties, to the custom-properties.

-------------------------

Does anybody know of any code that would automate this process?
