[Feature]: Pull and manipulate all cards from multiple boards that are in the equally named column in a separate synthetic Kanban board

[6-AND-9]

Goal or desired outcome of this feature

Be able to create a separate synthetic Kanban board which will pull cards from the equally named columns from other boards. Moving the card across columns in the synthetic board would move the card in its original board as well.

Describe the feature

I have several Kanban boards for different life domains. Sometimes I forget that I've created a card in this or that board, and it gets neglected.

In order to avoid this I'd like to create a new synthetic Kanban board that pulls all the cards from the columns with the same name (e.g. To Do, Doing, Done, Archive etc.). Ideally I'd first choose somehow from which existing Kanban boards will this data be pulled along with from which columns inside those.

The relation would work both ways, so if I move a card from To Do to Doing in the synthetic board, it will also move in the original board it is located in. EDIT: Cards will also have their tags copied from the original board, along with a new tag that is either the full label or a user-defined shorthand for the board from where they are pulled.

In this way I'll have an overview of all tasks that need to be completed across domains, instead of be forced to open each separate board and check for them separately.

Can you think of any alternatives or work-arounds?

As I don't know if this is currently possible, the only workaround is to manually copy the cards in the new synthetic board. But that defeats the purpose.
