Allow customization of sender email address on Time Based Events

Currently, the email address populated in Sender for any email action tied to a Time Based Event is linked to the first user account that created ANY Time Based Event in that schema. This can lead to confusion for the recipients when it appears a specific person is sending an email notification. Furthermore, as time goes one, that person may no longer even be with the client company, causing further confusion.

There is an option to change the default/generic sender email address in the global settings, but this affects ALL other email actions, which is not always a desirable approach to this problem.

The request here is to allow for customization of the sender email address for each specific time based event.
