Multiple Board Inheritance or Overlay

Question

Windows 11, VSCode, NCS v2.3.0 
 Hi, I have two custom boards that are very simple, but slightly different pin configurations from one another. 
 I have been using the adafruit_feather_nrf52840 board configuration for building both of them. I have an app.overlay where I have been commenting/uncommenting the right pin configuration. 
 Is there a way to define my own custom boards, but "inherit" from the adafruit_feather_nrf52840? Like, I would define minimal configuration that describes my boards differently than the adafruit_feather_nrf52840, but all the devicetree and config from adafruit_feather_nrf52840 still applies? 
 Thanks.

You can create a board-specific configuration file for each of your boards, then create a new build configuration for each board that includes their given board config. Or you can define new custom boards based of the Feather: 
 
 Create a new board via the "Create a new board" button in the "Welcome" pane of the nRF Connect VS Code extension. 
 Copy the dts and configuration entries from the adafruit_feather_nrf52840 board files into your newly created board files. 
 Make the relevant changes that you need to represent a base configuration of your custom boards in your new board files. 
 Create a new build configuration that targets your new board instead of adafruit_feather_nrf52840. 
 Repeat for how many different boards you want.
