Just visit the editing forms to add labels to existing plans and journeys, or add labels on the go when you create new ones.
Add or update labels to existing journeys by opening the Edit Journey modal.
Add and update labels to both new and existing plans through the plan form.
Once you've added your plan labels and journey labels, you can see them displayed under the plan or journey name. You can use them to categorize your plans/journeys and help you filter for what you're looking for.
