Photos edited on iOS iphoto sync with OS X iPhoto?

I understand how to sync photos from iPhoto on my MBP to my iPad through iTunes by checking the box to sync photos from my iPhoto library on my MBP.

So that gets the photos on my iPad. I like using iPhoto on my iPad to edit those photos (straighten, crop, etc...). When I'm done editing, I want those edited photos to replace the original in my MBP iPhoto library.

Is this possible, if so, how do I do this?
