New UX: page/context selectors on cards that synchronise with the elements on the page

It would be useful to be able to publish the page/context selectors as a separate card in the New UX boards so you can decide where on the page you want it to be located instead of being either at the top-right corner or on each of the cards/board elements. This request would pose additional flexibility as at the moment if you have the dimension selectors on one of the elements of the page it does not synchronise to the other elements unless you click on the items you want to sync.
