add element in a standard widget

[arturfra]

Hi,

how I could add an element (% visualization) on a standard widget (roman blinds move/stop) ? I need to watch the % of opened blind as I can see on the apple home kit, as you undestand I should modify the "Roman Blinds move/stop" to add a percentage visualization

thanks in advance for answering me

ps. I'm not a programmer, only if there's a fast way to do it or if someone could write it for me
