If you have a sequence that is already launched or created, and you'd like to view or change the SmartLists that are used in that sequence, follow the steps below:
Proceed to your Sequence Listing page and click on the sequence you would like to view.
Click on the Enrollment Tab, and then on the Automatic & Dynamic Icon in the upper right-hand corner as shown in the screenshot below.
Once the popup opens, you can view, add, or remove any saved smartlists from being used as auto-enrollment or auto-unenrollment filters for your sequence.
