This is very interesting, and something I think could be handled
fairly elegantly.

I think required=True would still be your best bet here. I'll explain
more in a moment on how this might work.

Well, kinda. Okay, time to explain.
What it sounds like you need is a pend() method, which will store all
the values in their current state, without validation. you must be
very careful when doing this, of course, so that the pended values
don't get used for anything except displaying the form again later.
I assume you already have a model somewhere you plan to store the
field's data, so just write a pend() method that does only that. You
can then, if you like, offer users a "Pend" button which will call
that method instead of save(). When they're complete, they would click
"Save" (or whatever) and the save() method would do all the necessary
validation and do what it's supposed to do with a complete form.
An alternative, if you'd rather not have a separate "Pend" button,
would be to process the form a little bit differently in the view when
the user clicks "Save". For instance:
if form.is_valid():
# The form is complete, so process it
form.save()
else:
# Save the current values so the user
# won't have to start all over again.
form.pend()
# But make sure to show the form again
# with the errors, so the user can fix them
Basically, you'd write pend() to take care of storing an in-progress
form, and save() for processing a completed form. Then you have a
couple options on deciding when to call which one. Also, I'll leave
pulling up a pended form as an exercise for you. It shouldn't be that
hard once you get the storage worked out.
