Add metronome to workouts (an old request...)

It would be great to enable a sound option that would play the role of a metronome for workouts that focus on changes in cadence. Zwifters could therefore easily follow the beeps to be sure they are at the right pace, especially when the sections are short and the change of rhythm is significant.
Thank you in advance for your interest and looking forward to seeing this new feature integrated into your software.
