Often you may have a task that you want to occur at multiple times. To save filling out all of the details from scratch, you can duplicate a task that has already been added.
Click the three dots on the right hand side of a task, then Duplicate.
This will load up a form with all of the options from the task you are duplicating already loaded. Make any adjustments as necessary, and Save.
When duplicating a task, you can control the recurrence type as well. This can be useful if you need to amend when the task should occur after task completions have already been added.
