Allow tagging or staring particular segments to review larer

I’ve found that relatively few segments during a day are really ideal for training, where I’m really focused, not too tired, it’s not too crowded, etc.

It’s hard to remember every run/segment, so it would be nice to be able to highlight particular segments to go back to and study on a break or after the day. Even better if it’s possible to do this via a voice command so I don’t have to get my phone out.
