I use Forte on most jobs that I quote. I understand how I arrange the headers, beams, and joists. By naming the levels it would be much more easier and quicker for anyone to look at the file and locate any item in question. I work with building that could be up to 5 floors. it would make it easier and quicker to find.
Use the Job Tree panel at the left side of the main view to drag and drop members to different locations in the tree. When you hover over a member or level in the tree an edit button will display that, when selected, will allow you to modify the name.
If you have many members (like 20+) this is incredibly tedious. This should be implemented: https://ideas.forteweb.com/ideas/FORTE-I-130
