In order to update this setting, you will first want to navigate to the Scheduler stage in the Workflow Editor that you'd like to make changes to, and scroll down to the 'Reminder Message' section.
Here, you can add the amount of time (in minutes) you'd like to bring forward. For example, to change your reminder to go out 3 hours in advance, type '180' in the highlighted box below. You can also send out more than one reminder message if you click on the "Add Another Message" button.
