Bulk edit for notifications

Hi all,

I’ve just upgraded from OF2 to 3, with a hefty collection of tasks in my database. I want to use notifications/reminders for a small subset of the tasks. But looks like when I enable notifications in ios, most of the pre-existing tasks get the due date set as the alert - I’d like instead for them all to be without notification, and only enable the ones I want.

But looks like OF3 on ios does not support group editing of tasks to change the notification (or simply activate or deactivate).

Is this possible, or am I being stupid (or perhaps both :)

Any advice appreciated!
