The "set to repeat" option is currently available only when users manually create tasks from the task dashboard. That said, having a bulk edit option would be invaluable to customers who are looking to create many new tasks or manage existing tasks.
Possible use cases:
Customers are on the Contacts dashboard where they bulk select contacts and hit "Create tasks" to create a task for each of these contacts
If customers already have existing tasks that they want to "set as repeating" in bulk.
How I can possibly see this happening:
1. Adding an option to "set as repeating" when creating tasks in bulk from the contacts dashboard
2. When checking multiple tasks on the tasks dashboard > "Edit", the user can also select "set as repeating" when selecting the task due date and reminder.
