Default material measure tag lists in openstudio application

edit

I am using the material measure tags to help identify materials in each assembly. I also noticed that I can manually type any tag I want and it can be reported. I have a couple questions related to default list of tags. (1) Is there any documentation on where the lists of materials come from? (2) Can the default lists be edited so that new materials that I want to add can included in the drop down list? Thanks.
