Multiple projects to one board?

Would it be possible to have either app wise or local server activated, a method for using different project screen pages to communicate with one board? It would mean multiple project authorisation codes referencing the same board code or multiple board codes logged and used from the same board at log on time.

Simpler would be the allowing of auth codes to be pasted into a project configuration, after having been generated by another when the whole project is initiated.

At present each project would need a separate board and bridging used to refer to the same board.
I would see this as a way of expanding the amount of ‘paged’ controls for a particular board, and the possibility of ‘private’ configuration pages etc, should an individual project page be shared.

Thought I would ask.
