When the list of tag answers comes up in Clinical Records, the clinician can add alternative answers in the free text box at the bottom and click 'Add This Answer' and the tag answer will then be available in this tag going forward.

Navigate to Maintenance, Branch & System and then System Parameters. Under Exam/Clinical, there is a 'Allow Adding Tags on the Fly' checkbox.

When this box is ticked your clinician can add tag answers to the list from the options box.

If the box is unticked, the clinician cannot add new answers to the list for future use.
