LOCATION ability to add sub-states

Hi we need to add more options for Location properties to search and more specific about where exacly are.
So we need something like this:

Country->State/Province->City->Sub-state e.g Greece->Central Macedonia->Thessaloniki->Center

Is there any way to do that with ossproperty?

Hi,
Currently, OS Property doesn't support deeper location level. Just have 3 location levels: Countries -> States -> Cities
Thanks
