Is your feature request related to a problem? Please describe.
To me, large Decks are sadly quite unusable from the Tasks app, don't know how your workflow is in this case/what the current benefit of having the Decks in the Tasks app is.
The main problem is, that all cards are shown as tasks and not only the ones that I'm assigned to. For me the idea of a task is, that I only want to see it if I have to take care of it. And when I want to have a project overview I go to the Deck app.
Also the mobile task clients are overwhelmed by the massive amount of "unnecessary" tasks.
But maybe I am just using it wrong 😅

Describe the solution you'd like
Maybe it is possible to have in each board a toggle (just like the Due dates reminder one) where one can switch between Sync all cards to the Tasks app and Only sync assigned cards to the Tasks app. This would also avoid to break compatibility for users who prefer the current implementation.

Describe alternatives you've considered
Not using the feature of showing decks in Tasks app at all.

Additional context
None

Start by tracing how Deck cards are synchronized to the Tasks app and where board settings such as Due dates reminder are defined. Compare the current all-cards behavior with the requested assigned-cards option, while preserving compatibility for boards that retain the existing behavior. Done means a board can choose either sync mode and the selected mode is respected by Tasks clients.
