Iowa DOT denotes different types of sheets by an Alpha destination. https://iowadot.gov/design/dmanual/01f-01.pdf
The plan set sheet number does allow for the definition of an alpha numeric value such as "C1" "CIV-001" "2CX45" however due to the uncertainty of the values we do not auto increment this value and it has to be entered for each sheet.
