Is It Possible to Have Nested Kanban Boards?

We’re looking to use Wekan to represent work at the Portfolio, Program, and Feature levels with a hierarchy that explicitly linked the capability cards placed in a Portfolio board linked to Cards in a Program board that are then linked to Cards in Feature Team boards. Is this possible?

When you are creating new card, there is also option LINK that links to card that is at another board. With it, you see contents of card on both boards, and changes affect boths cards.
