Telegram: Send multiple Pictures in one service call

Configuration

Hi Guys I am currently decluttering my Automations and I wanted to send x Pictures at once with one service

I currently have following services in my Automation:

  - service: camera.snapshot
    data:
      filename: /media/door_opened_1.jpg
    target:
      device_id: aaa
  - service: camera.snapshot
    data:
      filename: /media/door_opened_2.jpg
    target:
      device_id: aaa
  - service: camera.snapshot
    data:
      filename: /media/door_opened_3.jpg
    target:
      device_id: aaa
  - service: camera.snapshot
    data:
      filename: /media/door_opened_4.jpg
    target:
      device_id: aaa
  - service: camera.snapshot
    data:
      filename: /media/door_opened_5.jpg
    target:
      device_id: aaa
  - service: telegram_bot.send_photo
    data:
      authentication: digest
      caption: '1'
      file: /media/door_opened_1.jpg, /media/door_opened_2.jpg
  - service: telegram_bot.send_photo
    data:
      authentication: digest
      caption: '2'
      file: /media/door_opened_2.jpg
  - service: telegram_bot.send_photo
    data:
      authentication: digest
      caption: '3'
      file: /media/door_opened_3.jpg
  - service: telegram_bot.send_photo
    data:
      authentication: digest
      caption: '4'
      file: /media/door_opened_4.jpg
  - service: telegram_bot.send_photo
    data:
      authentication: digest
      caption: '5'
      file: /media/door_opened_5.jpg

It works pretty solid but it is pretty nasty to maintain it in case I want to change something. And since I want to improve my skills I can maybe use the new aquired knowledge how to do it better in my future projects.

Therefore I have following questions:

Does anyone know if it is possible to define multiple files in one message?

I looked up the docs but they always mention file (not “fileS”) but they dont explicitly say that it is not possible so Im just curios.
Also the Forum always mentions single files but never multiple files (at least I didnt find anything)
Thanks in advance.

Trying to do the same. Did you find a solution by any chance?

Nope. Undortunately not.
