You will need to do this on the app, not the website. Select the option to modify existing fast pass, then select the attraction to modify (the one you are least attached to for that day!). On the next screen, you will have the option to select some or all of the party that currently shares this FP. Select one member of your party at a time, then you can search from all available attractions that day. (Note that even though the app will say that it's only searching from available attractions in your existing return window, it's actually searching the entire day.) The app will put you into a return window that is close to your existing time, if possible, otherwise you will get whatever is available. Repeat for all members of your party. Once you've secured the new FP+ for everyone, you will use the modify option again to search for return times that overlap. When I was using this method to search for A&E, I would first select all 4 of us; if nothing popped up for 4, I'd search for 3. Then 2, then 1, in the hopes of at least getting 2 or 3 that had the same return time. The process may take a few days, so be patient and persistent! There are also cancellation threads out there as well, where folks will post FP+ they are looking to trade or drop. Just search for your month of travel plus 7DMT and you should find it. The one for October is for both A&E and 7DMT - not sure if November is the same. Good luck
