And if all you want to do is assign different properties to different sets of elements I highly recommend setting subdomain_ids on elements and then just using those to infer what material properties should be used on each element.
If you build your meshes with something that outputs Exodus meshes... you can create element "Blocks" that are assigned subdomain_ids... which will automatically get read in and assigned when you read the mesh. I'm not sure if any of our other mesh formats (besides xda obviously) support that.
