After they are created and saved, Route Modifiers can later be moved from their current set to a different set. To move them:

1. Open the Route Modifiers set that contains the avoids/favors you would like to move.
2. Check the boxes next to the individual modifiers you would like to move or click Select All. A Move button will appear.
3. When you click Move, a drop-down will appear where you can select the new set where you'd like to move the selected modifiers.
4. Click Move to finish moving the modifiers to the new set.
