Meetup with friends and custom Route

What is the best practice to get a group of friends together and preview a custom made route? In meetup view, the worlds and maps are fixed and there is no way to disable the automatic turning. Kindly suggest the least troublesome way as the number of riders is around 10. Thanks.

The only workaround I can think of is using the “ride with” function when selecting a world to ride. All of you would have to choose to ride with one person in the group and then make manual turns. Everyone would have to know the route and what turns to make.
