Meetup rides on 'closed course'

Sorry if topic has already been brought up. We’re having a problem in the ‘Meetup’ feature staying together. We are losing site of riders (even though we are only 4 riders). The names of the ‘riders nearby’ on the right side of the screen are so jam packed with other riders on the course we spend most of our time trying to stay together instead of enjoying the ride. Are there any plans to add an option to have your meetup group ride on a ‘closed course’ - so we can ride alone? or even to have the names of your meetup group stay highlighted on the right side of screen so you can easily see how far each rider is ahead or behind?
