Showing flags is possible on a reference audit. Much like pseudo courses, course flags are used for comparison against potentially matching courses. Course flags are encoded first on a requirement in the CFLG field (see screenshot below) and will search for a match in a course's IFLAG field:
Setting a CFLAG on a course within a requirement automatically instructs uAchieve to look for a match when it runs an audit. In transfer articulation, the course flags are encoded on the Flags tab of the transfer rule.
When uAchieve finds this match encoded on a TA rule, it knows to process that rule and display it accordingly on an audit.
