Define property for family of devices

Hi,

Is it possible to set property values differently for each device family?

I have setup resource directory for different families, for example "resources-round-454x454". Below I have a directory for drawables with drawable.xml and one for settings with settings.xml. The drawables get processed correctly, but for settings always the settings from the main resource directory get used, the one for the family are ignored.

Should this work and I am just doing something wrong, or does the family qualifiers do not work for properties?

Regards, Robert
