Booking fast passes for other people/ combining parties

[summer_disney]

Hi all,
We are booked to go to WDW next year with some family members. We are all going on the same dates and staying in AKL, but booked individually . They aren’t planners and have asked if I will book all our fast passes and ADR’s together.
How would this work, will Disney let me do this? Obviously on my Disney account I have my husband and children’s profiles to book for, is it possible for Disney to connect my family members reservations to mine so I can book the whole party at once?

Also, with 60 day fast passes, is it 60 days from check in date that you can book, or 60 days from the first park day (which would be the following day)

Thanks!

Yes just link all the tickets in the mde app.
You can add or leave out whoever for whatever for each fp or adr. Sounds complicated bit is self explanatory once your all linked.
