"Corrected coordinates for mysterys but not for other cachetypes"-filter?

The current options for filter under "Corrected coordinates" is Any, Yes or No.

Something I would find useful is an option that allows me to show all mystery caches with corrected coordinates but also all other cachetypes without corrected coordinates. Yes, I could make an offline database of a list/search, but sometimes I would prefer to have this on the live map.

So my suggestion would be to have two buttons, one that affects all caches and one that affects only mysterycaches. This way one could set "all cachetypes" to "Any" or "No" and then set mysterys to "Yes" to get a filtering without the clutter of unsolved mystery caches.
