Tagging subitem owners using @everyone

Hi everyone,

Not sure if this feature is not available yet, or if I am missing something but, does anyone know if the below is possible to achieve:

  1. When using @Everyone on this item tag in the comment section of an item, I want everyone who is assigned to the parent item and subitems to receive the notifications.
  2. When using @Everyone on this item tag in the comment section of a subitem, I want only people assigned to that subitem to receive the notification.

Currently neither seem to work for me.

Any advice would be very much appreciated.

Many thanks,
Ellie
