Climb Portal Ghost Selection

When a rider selects a climb portal ride, allow the rider to select one or more ghost riders to compete against, similar to strava live segment KOM on computer head unit. Ideally I could select someone I follow or my PR or best time in last 30 days. Usually there are some sort of ghosts auto selected, so the request is to make the feature more user configurable, so the ghost better reflects the effort I am looking to do.
