I have the exact same need and find it strange that this isn’t already an option.
Since we can already assign a Team to a People column it makes sense that an automation should allow the someone in “Assigned to someone” to be a Team.
I would also like to use this feature, in order to be able to create a To-Do in my personal to-do list board. This way, it is possible to track my own contribution, whereas I cannot change the status of the item in the board where the task is assigned to my team (because each member of that team is suppoed to do this task independently)
I have the exact same need. This would be extremely powerful also because that will allow for us to trigger channels to be triggered in Slack with that criteria on an automation.
