Yes I would use the same label on many views like Cross Sections, Details etc. Below are a couple of views from the sample plans. All the text labels on those views wouldn't have to be all typed right? Except the original one.
From what i read macros don't work on materials? You couldn't use a macro to automatically describe how to build something?
As I said earlier, can all those labels be saved somehow for use in that plan again (copy and paste?)and in future projects, re a database in the library?
