As a stakeholder, you can convert a task to an activity. You may have created a task and then realise that it should be a much bigger activity as there is a lot of information that is attached to it.
Quick Steps
Select the settings icon beside a task within an activity in the diagram content menu, magnifying glass or when the map is hidden
Click Convert to Activity
Change the description of the activity if needed
Click on the green Convert to Activity button
What happens when a task is converted to an activity?
The role of the initial activity will be kept for the new activity
The task description (unless changed) will become the new activity title
Alternate paths and gateways are not affected
Any new activity will be added to the end of the process
