Ability to use columns (coming from connected board) in the message setup of notification sent through automation

Hi all,

Through automation, we can notify peoples, great.
We can setup a custom message using the fields of the related record, great also.
But seems we cannot use fields coming from a connected board (linked to the related record).

Does it exist a native way to do that? If not, could be a great feature to be implemented from my point of view.
