NEW UX: Ability to adjust the distribution of height in vertically stacked cards

Currently in New UX when I stack multiple cards in a column, they all have exactly the same vertical height, no matter what.  I'd like to be able to spread the height distributions of vertically stacked cards to better fit the cards' contents.  i.e. give height to cards that need it and less to those that don't. 

Hopefully the image helps explain what I mean...
