How do you modify FP?

I have my FP reserved for the parks. Last minute vacation so wasnt able to get all the FP we wanted. I see all my reserved FP, but how do I check if anything more has opened up and modify it? Thanks!

When using the app, view your FP selections and tap the one you want to Modify. Choose Modify and continue with the process.
