There's a couple things to do for that. First, you can use an actual text label to mark out SPECIFIC trusses obviously. But the other thing you can do is make a simplified version of the truss report and include it in your layout views.
Yes thats what we normally do. Just wanted to be like fixtures tooltip, Turn on and all your truss automatically labeled for reference.
That would be an awesome feature to add, especially if you're using custom pieces from various manufacturers to make something unique.
