Option to change icon for cover - state open and closed

Hi
I use Roller shutter in Home Assistant. But default icon is not friendly for me… because icon show windows but i want use icon name: mdi:window-shutter and mdi:window-shutter-open
It looks for me as my shutter.
In defualt config home assistant i can not change this icon.

Now i change it by install custom card name: Config Template Card by HACS
Then add manual card with this config:

card:
  entities:
    - entity: cover.roller_shutter_for_ha_0_1
      icon: >-
        ${ states['cover.roller_shutter_for_ha_0_1'].state  === 'open' ?
        'mdi:window-shutter-open' : 'mdi:window-shutter' }
  type: entities
entities:
  - cover.roller_shutter_for_ha_0_1
type: 'custom:config-template-card'

Default icon looks as:
Default

When use Config Template Card:
custom

All will be ok but when use custom card i can not add it to my standard default ENTITY CARD Home Assistant. Now i must use switches on Entity Card and Rooler Shutter on Config Template Card.

Good will be add feature in Home Assistant to change icon for cover on deault card in Home Assistant. It is possible ? Please…

Did you take a look at customization?

yes and i try this but not working:

cover.roller_shutter_for_ha_0_1:
  templates:
    icon: if (state === 'open') return 'mdi:window-shutter-open'; else return 'mdi:window-shutter';

This is add in customize.yaml

also try this and also no working:

cover.roller_shutter_for_ha_0_1:
  templates:
    icon: >
      {% if is_state('cover.roller_shutter_for_ha_0_1', 'open') %} mdi:window-shutter-open
      {% else %} mdi:window-shutter
      {% endif %}
