Hello Mike!
All of the sheet numbering in the title blocks included with ConDoc are set up using auto-text. You can find the settings under LayOut > Document Setup > Auto-Text.
The sheet numbers are on the shared layer title block. I think the best course of action for you is…
- unlock the Title Block layer
- right-click on the sheet numbers, move to the Annotations layer
- Copy and paste the sheet numbers to each page
- manually change the sheet numbers to whatever you like (E, M, A, etc)
If you are up for it, you could dig in on auto-text and probably figure out a clever way to save some clicks.
Let me know how it goes!
Mike
