This could almost be implemented using existing features of Equipment. If you make a new equipment group called 'keyed notes', you can then make a piece of equipment called '1' and put the note in one of the description fields. The equipment block could be a point or other non-plotting item. A custom block can be made for the equipment tag with an attribute that displays the name of the piece of equipment, in this example '1', say, in the center of a circle. All there is left to do is insert the 'equipment' on the drawing to get the equipment tag which looks like a keyed note (circle with a 1 in it) and put an equipment schedule on the drawing, which would only show the equipment name (keyed note number) and the field with the description in it. The only rub is that you can't insert more than one instance of a piece of equipment, so if you copy it you'll get more than one note 1 in your keyed note list.

With the new Beta version having triangle, Square, and Hex numbers for the feeder, it would be nice to use those blocks and numbering sequence for a generic key, reference, general note scheduler. That way I don't have to use the LV and create a block for each number like I do now.

I have a key note, reference note, and general note already set up in designmaster. It is done through the LV schedules. I create a block for the notes 1-20 using a triangle and hex with the number. I just place the schedule with all devices if it is general notes and then the placed device if it is keynotes. I rearrange the schedule to show only the note number and the note with title. I guess the only thing I wish would be that it was able to have a selection list of symbols such as circle, box, triangle, and hex that I could associate with the schedule and it would automatically increment the numbers in them.

Consider using the table feature and an excel spreadsheet...
