Fastpass Plus Changing Park Day

[JLTraveling]

Hi all...longtime annual passholder just jumping into the Fastpass Plus fray. I have a question that I haven't seen addressed anywhere (though I may have just missed it). I know I am limited to 3 per day, all in the same park. I know within that park, I can change reservations on the fly. But what if I want to go to a different park altogether on that day? In other words, at 60 days out I book 3 Fastpasses at Epcot. But at 15 days out, I decide I'd rather go to Magic Kingdom that day. How do I cancel all three Epcot reservations and turn them into MK reservations? Does the answer change if I wake up ON my Epcot day and decide to go to MK instead?

I've only just started playing with the system, and I made three sample FP reservations at Epcot for today. Now I can't see how to cancel them, and I can't see how to change them to a different park. Please advise!

We did something similar in Feb. Late one night we decided to switch from Epcot to AK and changed all of our FP+ from the hotel using the app. Cancelled all three, added three new ones. Went off without a hitch.
