Custom:auto-entities - show entity and specific attribute

I am currently using a Custom:auto-entity card showing a list of my steam wishlist that are on sale.
It gives the following display

I would like to display the actual sale price rather than ‘True on sale’

The code I have is as follows

type: custom:auto-entities
show_empty: false
card:
  title: Steam Wishlist On Sale
  type: entities
filter:
  include:
    - entity_id: binary_sensor.steam_wishlist_*
  exclude:
    - state: 'False'
sort:
  method: name

Is it possible?

thank you.
