Here is how I made an implementation: Once a dish counter is started, you can long-press on the green/orange timer (short press will still pause the timer). It will show a banner that a stopwatch is activated. Repeating that will deactivate the set stopwatch function. If the stopwatch function is activated and the timer countdown hits the alarm, the green timer will turn into a yellow stopwatch timer, which then can be paused or stopped. I think that should serve the basic testing purposes you described earlier.
