Archery Timer for timed end practice and bow training?

I would like a tool to be added so that you practice shooting under timed conditions (10 sec lead in, however much time per arrow you want to practice and how many arrows and a countdown when you are running out of time (10….5….321 in beep form would be nice) Bonus points if the timer also has a bow training/reversals feature for strength training. Essentially, an archery specific tabata timer ☺️
