Energy Distribution Card Entity From Group of Individual Devices?

Hello,

I am using the custom ha-emporia-vue integration. That all seems to be working awesome I can see my energy usage and all my devices.

Is it possible to create a custom circle in the Energy Distribution Card that would represent all the power used for Heading/Cooling? I have many devices that just monitor the power usage for the various HVAC systems. It would just need to add all those up and display the sum in the Energy Distribution Card.
