Adding a stop number to an object will allow a user to discover the object via the Keypad on the iOS or Webapp.
1. First Step
Open the object page you wish to add a Stop Number to.
2. Second Step
Scroll to the bottom of the page and open the "Advanced Options" section.
3. Third Step
Under 'Extras' add the number (0-999) for the object. The stop number has to be unique for your collection (not just a specific tour).
Click save and you are done.
