I tend to use a lot of large sheets with contributors from multiple sites interacting with the sheet through reports, and use automations to notify users when they need to input information in their report. Unfortunately, the notifications link back to the sheet itself and not to the user's report. It would be very useful to be able to customize the link in the notification so it would point either to the sheet or an existing report. Hyperlinks within the message don't reliably work either, so this would be a more native approach.
This could be expanded to improve the ability to prompt users to complete tasks in other sheets - for instance, using a reminder to prompt a user to fill out a form by including a message and linking that form in the notification.
