Min_Max sensor getting entities from group possible?

Configuration
1

I guess that what I’m trying to do is not possible nowadays:

sensor:
  - platform: min_max
    name: env_indoor_avg_temperature
    type: mean
    round_digits: 1
    entity_ids: >
      {{ expand('group.indoor_temperature_sensors')|map(attribute='entity_id')|list }}

Any ideas for not having to hard write a big amount of temperature/humidity sensors for every min_max sensor? For now I’ve got 6 sensors for the same group of entities.
Thanks.
