Use of separate entities for charging state at card config level

[CDRX2]

Using a secondary entity for charging state is already possible at the individual entity level. However, this feature is not yet applicable at a card config level.

I suppose having something similar to the filter function but for charging state could be a possible approach.

please provide an example how you would see such configuration

I would imagine something like this:

charging_filter:
  include: # filters for auto-adding charging states
    - name: entity_id # entities which id ends with "_is_charging"
      value: "*_is_charging"

Exactly what I'm looking for. Please have a look at https://community.home-assistant.io/t/lovelace-battery-state-card/191535/157 for potential additional/helpful information.
