I would like to figure out if there are more options for the RSVP page, other than adding a meal. We are also throwing a Welcome BBQ for which I want people to RSVP as well as give a song request for our playlist. I can find these options if I use a google doc, but then it allows for just anyone to put their name, whether invited or not. Is it possible to add more categories to the RSVP or is there an easy way to embed the google doc?
