You can in a presentation file
Switch your browser filters to a Sequence
View. (it's the button that looks like a funnel on your browser
window).
Expand your Tasks and RMB over a sequence that you
want a different camera view for.
A form will pop up and in it you can select
Set Camera. Whatever your screen is showing when you hit the button will
set that view for that sequence.
You can then set up different camera views for
different sequences and you'll be able to zoom in and out for your
animation.
