returning "ride ons"

I would love to have the name of the person who just gave me a ride on get highlighted for a few seconds on my mobile app.  On group rides, would like to return the favor, but can’t find the person who just gave me the thumbs up.

Ride Ons can be given while the person is sitting on the couch using the ZCA. Just thought I would throw that out there.

Yes, I know.  I get them from friends that are not riding at that moment.  But on a group ride with 200+ people, it would be nice to be able to return them.  Could do that if  you could find them paging thru list in mobile app.  Also, on big rides the list of riders is constantly scrolling.  Hard to see anyone in particular.
