Show all entities of nested groups

Hi, I want to show all entities of a group that contains groups of entities is that possible? Right now I only get the subgroups and I have to click on each one to get sub entities

Like this:

window_lights:
  name: "Fönsterlampor"
  view: no
  entities:
    - group.livingroom_window_lights
    - group.guestroom_window_lights
    - group.kitchen_window_lights
    - group.bedroom_window_lights

guestroom_window_lights:
  name: "Gästrum fönsterlampor"
  view: no
  entities:
    - switch.aeotec_switch5_2_switch_55_0
