Currently, when users begin a self-service action, they must either complete it in the same session or copy the JSON for the self-service action to be used later. However, the latter option would necessitate that they complete the self-service action as JSON, instead of using the form (likely the most user-friendly way of using self-service actions)
For more complex self-service actions, it may be better to allow users to begin a self-service action, save it as a draft, and return to it later to complete. For example, if a user begins a self-service action, then must make a change to another entity in order for the self-service action to complete successfully.
