Double pass switchback for launch coasters like Pantheon

[DaMegaTaco]

It would be really cool if there was a piece meant to allow the coaster to pass through, switch the track, have the train roll back, pass through the switch track, go up a tower spike, and then have the switch track reset after the coaster goes past it one last time. Another option would be to create an option for the switch track to allow the coaster to pass by the track a customizable number of times before resetting. That way it would be possible to do those rollback tower spikes into a secondary launch that coasters like Pantheon use,
