Continue timer when not pedalling

Hello!

When doing a workout and not pedalling, the timer stops. How can I make it go on while pausing?

I ask this, because I need to do tests which require not to pedal a moment before sprinting. When the timer stops, the workout gets out of sync.

Thanks!

Also have this problem when measuring lactate between sets. The workout gets out of sync with the TrainingPeaks workout, so analyzing in TP after the workout is done becomes more difficult. Zwift, an option please?
