Total Number of Sheets?

As long as I am working on the title block today, I have another question:

Is there a way to get the total number of sheets? The sheet numbering is simple in this case: 1, 2, 3, 4 etc. I don't have Civil, A4rch, Electric, etc. sheet numbering to be concerned with.

What I want is to automatically number the sheets like so: 1/4 for sheet 1 of 4 total sheets.

Every project will have a different number of sheets. I could link the last number (after the /) to the last sheet created once the last sheet is created, but that would mean I would have to edit every title block on every sheet? I don't know - I'm asking.

What I want is to create a one-sheet dgn, with fields or links that populate the sheet number: <current_sheet>/<last_sheet>. The first sheet is copied as needed until we get to the last sheet.

Is there a field or way to link to whatever the last sheet number is?
