Default Hide navbar from only homescreen?

I have searched high and low and tried many different things. Most modules I have found hide both the statusbar and the navbar and leaves the gap between my homescreen dock and the bottom of the screen as if the navbar was still there. I'm looking for some way to only hide the navbar from nova launcher as if i was to disable it (pushing my dock to the bottom). I know its not that big of a deal but it literally keeps me rearranging my homescreen everyday...please help!
