SHORTCUT KEY TO START COUNTDOWN

I know there is a shortcut key to open the countdown, but it would be great to add a shortcut key to start a specific countdown. We use a countdown to start the service, and we are always looking to streamline processes. Its 5 clicks to start a countdown - it would be great to start/stop it with one! Especially as we have a stream deck it would work great if we could integrate a countdown start with that. Appreciate your consideration. Many thanks for all the great work!
