Fares can be edited by selecting the Fare's name from the Fare Dashboard.
Adding/Subtracting Rider Categories
Rider Categories can be set from the Rider Categories menu. Adding or subtracting a Rider Category affects all Fares. There is no way to have different Rider Categories for different Fares, only different costs.
Editing a Fare Rule
Fare Rules can be added or deleted or edited, depending on the changes needed. If editing the Fare Rule instead of creating a new one, make sure the Fare Rule does not copy an existing Fare Rule, especially if using Fare Zones and Reversible is employed.
