Please indeed. Was expecting to find this, disappointed that it's not available. Need to be able to run stats. on closed tasks to determine which buckets they visited in their progression (and which they skipped), would be relatively easy if I could trigger on bucket change to write-out a SharePoint list item.
This feature will enable many possibilities to manage the team/project tasks.
My goal is to have a SP List 100% updated with the tasks of the team and also conected to a PowerBi dashboard with the overview of all my projects. The only thing missing is that trigger when a Card is updated or moved to another bucket.
