LEJOG route

Hello, first off I just want to say this website has to be the best routing website ever... I have been having so much fun with it lately. I am riding LEJOG this coming 20th of August and I am choosing your route. However I have one question about making routes. I have planned the full route and chose the campsites using your feature :) so now I need to make routes for every single day so that I can load them onto my gps device. I can't figure out a way of doing this unfortunately. Essentially what I need to do is delete all waypoints that come after or before the day's route in question so that I can have "day1" "day2" on my gps device. Thank you so much again for this service.
