Set for next nn records (User Flags=>Set next nn)
Choose this option to set the user flag for the next nn records. This will set the user flag for the current record, and then the next nn records in the current sort sequence. This will help you to easily set filters like the first 50 records in any order. For example you may have your current sort order set to distance (miles or kms) and would only like the first 200 closest waypoints.
Note: Negative numbers are also supported. This will enable you to set the user flag for the current record, and the previous NN records.
