Hi,
To limit the number or rows in an inline, max_num is usually the way to go.
https://docs.djangoproject.com/en/dev/ref/contrib/admin/#django.contrib.admin.InlineModelAdmin.max_num
As far as having the list of all possibilities available as options goes,
it gets a little more complicated and I don't think it's something the
admin really handles out of the box. You're starting to get to a
complicated enough case where it might make sense to roll your view and
form code.
It might be possible to do it with a custom form and the proper "initial"
argument to your formset.
