MaxScript question: Vray materials from .MAT files to scene materials

[Haider_of_Sweden]

I am building a library, .MAT-file, with vray materials that I use over and over again.
When I link in a Revit-file into 3dsmax, materials come in as Multi/Sub-Object material.

Now, in 3dsMax Material/Map Browser, you can right-click on a library-file that you have loaded in and pick "Update Scene Materials from Library"
Unfortunately, it cant see the materials inside Multi/Sub-materials and so I cant update scene materials without hassle.

Can someone please help with a maxscript that fixes this problem?

Here is what we got to in the end.
Anyone else with the same issue, feel free to give the script a go, and modify it according to any need of yours.
