Saveable cards - centrally updateable designed cards - referenced cards

Can we have the possibility that when we create a card, that it is saveable as a card that can be referenced in other dashboards or on other pages etc.
This means the card can be changed, updated, edited once and is reflected in all the other used places.

This goes hand in hand with being able to assign a dashboard to a user that contains cards that are the same as other cards on other dashboards for other users, you dont want to be updating each individually.
