The Paste Text and Map Fields and Tables function contains the ability to add content from a second worksheet into a N1 Report document.
By default, a Narrative1 report file will only be able to automatically merge the data from the default worksheets, and not any copies you've made. For example, if you created a second or third Land Grid worksheet, only the first Land Grid would automatically merge into your report. The Paste Text and Map Fields and Tables feature can be used to automatically import additional worksheets.
The function can be accessed from the N1 Ribbon in Word.
