From version 5.15 beta1, you can perform bulk actions on selected tasks in the Scheduling / Bulk action tab.
To be able to perform them, you need to have the necessary permission for the tab (Settings / Administrators / Administrators).
On the left, you can find several filters that you can use to specify those tasks on which you want to perform one of the available actions.
On the left, you can also find a magnifying glass icon. The number of relevant tasks is displayed right next to it. When you click on the icon, a list of the tasks appears.
On the right, you can select the action you want to perform (Close, Delete, Open or Transfer).
If you choose the Close action, open tasks from the list will be closed.
If you choose the Delete action, all tasks from the list will be deleted.
If you choose the Open action, closed tasks from the list will be opened.
If you choose the Transfer action, open tasks from the list will be moved to a different date. The time will remain the same.
