Customize shutter display

Hello !
I’m trying to improve my shutter card. That’s what I have today :


And the code looks like this:

type: entities
title: Volets
entities:
  - type: custom:fold-entity-row
    head:
      entity: cover.volets_rdc
      name: RDC
    entities:
      - type: custom:fold-entity-row
        head:
          entity: cover.volets_sejour
          name: Séjour
      - entity: cover.shutter_rdc_wc
        name: WC
  - type: custom:fold-entity-row
    head:
      entity: cover.volets_1er
      name: 1er
    entities:
      - entity: cover.shutter_chambre1
        name: Chambre 1
      - entity: cover.shutter_mezzanine
        name: Mezzanine
      - entity: cover.shutter_sdb_1er
        name: Salle de bain
      - entity: cover.shutter_chambre2
        name: Chambre 2

All is working perfectly. I “just” want to add a button on each line to close the cover(s) to 95%.
I have no idea how to do that. If you have any idea on how to do that, please share it :smiley:
