I plan on attending, but there are two possible shotgun riders. How do I handle contingency:

1. Fill out two waivers, with me primary on both and each shotgunner sign one each?
2. Fill out one waiver and add a third particpant block?

My concern with (1) is will the second one override the first one (this might happen if they are using a database to hold/track waivers), or will they maintain BOTH so I can use whichever one I need.
