Trigger notification when a change to a custom form submission is made/saved

Description -

Why is this feature important to you - We utilize custom forms to intake work across our company. However, there are occasions where the original requestor will go in and make changes/updates to their initial request form submission. If they make material changes to their request and save/re-submit, no notification is triggered, so the person assigned to the work does not know about the changes. This can cause us to work on things that then need to be redone/changed to correspond to the updated request.

How would you like the feature to work - Expand notifications for users to enable instant notification when a custom form is resubmitted/saved and the user is either on the routing rules for that custom form or subscribed to the issue/request.
