Is there a way to get a summary of time spent on slides during a record ?

Hello there :-)

I'm currently evaluating slidev for some of my trainings/talks as it looks very nice (congrats for the nice work !) and I'm wondering if you know if there is a builtin feature (or a plugin somewhere) allowing to tell me time spent on this or that slide (or even an overall section) during a record ?

Bonus point would come if it would be possible to define aimed durations allowing to show an indicator on presenter mode, telling me if I'm ahead or behind schedule in realtime.

This would be very valuable when you speak at conferences where time is constrained and you need to adapt in case your too slow or fast.
