Capital letters in the menu

Hi,
when i create a dropdown navigation menu, the title attributes start automatically with a capital letter (when they consist of two words). I need the second word to be just lower case letter. Example:
Main menue button: Region. Drop down menue under this parent button: Central Region, North Region etc. I want it to be Central region, North region. Is it possible please? Thank you!
