Feature request: Autoassign new cards to logged in user

I am considering moving my Trello tasklists to Nextcloud. As I use shared tasklists (e.g. a family and household list together with my wife) all tasks/cards are assigned to one person. It would really help if new tasks/cards would be automatically assigned to the user which creates the task/card. As the cherry on the top, also the due-date should automatically be set to today - but this is far less important as the person assignment. Unfortunately there is (still) no easy workflow engine possibility to fulfill my need.

The issue names no files, tests, or entry points. Start by tracing where new Deck cards are created and the logged-in user is available; the work is done when newly created cards are assigned to their creator, with the optional due-date behavior addressed separately.
