In the “Flow Management” page under the Admin Panel, you should be able to create new flows as well as edit existing ones.
In order to edit a flow, click on the flow you want to edit and you should see a list of all of your stages in order.
Near the bottom of that page, you’ll see an option for “Remove Stage” and “Add Stage” – this is how you add or remove various stages within that flow.
If you want to create a brand new stage and implement in a flow, you’ll find the option for “Create Stage” near the top of the list.
Once you create a new stage, you can add it into a flow using the “Add Stage” button.
When adding and deleting stages within a flow, make sure you update each stage’s transition to reflect the changes.
To change a transition, click on the individual stage within the flow list and you should see the option at the bottom – keep in mind you can have multiple transition options for each stage.
(The visual sorting order – i.e. the drag and drop ability to re-organize the stages within the flow list – is purely visual and is not directly tied to any transitions).
