I am the admin of a Trello Workspace for our work, and in an attempt to free up licenses we need to delete users who have not used Trello in a set period of time. If the user was a sole owner of the board then we do not want to lose those boards in case other users were using them. Is there a way to automate it so that when a user is deleted, any boards that they are sole owners of have the ownership transferred to me?
