[Tex/LaTex] Beamer: Hide Backup Slides from Navigation Panel


I have some slides, which are not part of the main presentation, but can be shown if the audience asks some questions and I have put theses slides at the end of my presentation. I am using the Frankfurt theme, which adds navigation circles for each slide under the section titles. The problem is, that the backup slides also show up as navigation circles. How can I get rid of the bullets for these slides only?

Normally I could only get the navigation circles to be shown, if I added a subsection before the slide which I wanted a circle for, but lately the circles are added for every slide regardless of the definition of a subsection.

Make an appendix. Example (also handles putting appendix frames under a different counter):
