Yes. Override save_formset for the ModelAdmin containing the inline:
http://docs.djangoproject.com/en/dev/ref/contrib/admin/#django.contrib.admin.ModelAdmin.save_formset
Note the formset.save() only returns the modified objects -- the ones that
based on data changing appear to need to be saved. You'll also need to save
any of the initial forms (formset.initial_forms) that don't appear to be
modified, if you want to save all of the objects even if the form data has
not changed from initial values.
