Customized "Deal Cards" in Deals Dashboard

I want to set up my own cards and assign fields to them so that the About card isn't a dumping ground for every single field that I create.

 

Custom cards for things like fields for tracking commission payments on sold deals, additional personnel such as system engineer or implementation lead assigned to the deal to work the the deal owner, or a card for additional financial information about the deal such as third party costs the deal will incur, etc.
