PEO Appointment for over 18 dependant child

[longhorn1]

I am eligible to apply for ILR in February 2013 along with my two dependant daughters who are now over 18 under HSMP (2years) + Tier 1 General (3year).
They are still both my dependants (in Uni) but by the new rules they are applying separately using the SET(O) form.

My question is:
Do I need to make individual appointments for each of us? We want to go as a family.

Kindly advise or share your experience please. It will be virtually impossible getting appointment for 3 of us on the same day if we have to book individually.

Thanks,

Longhorn1
