When a court configures this feature an additional pull-down menu is added to the 'Add Document' screen allowing the filer to identify the 1st, 2nd, and so forth qualifier of a particular type of document.
Most courts do not used qualifiers. This feature was designed for courts that qualify the standard document type codes such as the '1st' Amended Complaint or '2nd' Amended Complaint. Most courts use the document type code of Amended Complaint and don't distinquish which number the ammendment is.
