Is there a way to assign matID map via QML?

Hi,

I'm trying to assign a ressource map as a material ID map on a textureSet.

AFAIK, we can read this info via "structure" call and it return something like this:

"additionalMaps": [
{
"urlToBitmapRes": "resource://project1/matID1001?version=69243b1c31ded77dfd7e7181c89428a9083a188f.image",
"usage": "DataAdditionalMapUsage_ID"
}
],

I would like to do the opposite.

Thanks!
