Generate an Entity Card with all available entities from a single device

HI, id like to know if we can get a more easy to manage funtion like:
Select all items in Settings → Devices → Entities
To select all items i have here and grab them and put them all togethe with a few easy clicks so its easier to manage what you exactly wanne show up in the lovelace.

Or the ability to create a entity card an select as root the sensor.v2266a_ and slect all you want in that card. beacuse the GUI is a bit hard to see what ur adding and memorizing all stuff i already added.
