hehe.. I guess there goes my ideia! thank you for your input
there is something what might work but...dwg will be huge and heavy.
1. create a copy of ALL objects
2. when you create your Note1 point go thru all copies and add Xdata (Note1).
3. rename (with copy) all blocks to name_Note1
4. when add another NoteX follow step 1-3
using visibility properties show/hide notes with xdata
