title: How can I display a Django admin inline model within a fieldset?
body: <p>Consider the following ModelAdmin. In this instance, I'd like to have the inline "Book" UI display between the "None" fieldset and the Notes fieldset. Is that possible?</p>
  
  <pre><code>class AuthorAdmin(admin.ModelAdmin):
      inlines = [BookInline]
  
      fieldsets = (
              (None, {
                  'fields': ('author_name', 'date_of_birth')
              }),
              ('Notes', {
                  'fields': (['notes'])
              }),
      )
  </code></pre>
