Similar to how the Customisation > "Display Custom Field Value under Project" currently functions, it would be useful to be able to add a Project custom field to the notifications which goto resources when they are scheduled upon a project.
At the moment these notifications are limited to Name & Booking Category. Permitting the addition of a custom field would fulfil multiple use cases. In my current use case it would permit me to publish the Project Code / ID of a system I am integrating with HubPlanner.
