HotLink ifc surface attributes mappping

AC19:
I have several MEP IFCs (proxy elements) imported to modules
and modules hotlinked to main pln
now in 3d material colors mixed up

The question:
How can I add [MEP_IFC_NAME] to the name of each created IFC Material when importing ifc?

As I see it:
Color Name
[RED ] [MEP_IFC_NAME_1 IFC Material]
[GREEN] [MEP_IFC_NAME_1 IFC Material(1)]
[BLUE ] [MEP_IFC_NAME_1 IFC Material(2)]
