How to flip in/out off page connector in OrCAD
Yes there is! I learned this recently and now use it all the time. 

Select an off page connector then right click. In the context menu at the bottom there is a More... menu. Inside that menu you'll find all sorts of "Replace [In/Out] OffPage from [Left/Right]" among other things.

In the example you gave you would select "Replace In OffPage from Right"

You can select as many at a time as you want and do them all at the same time!

You can also add the appropriate off page connector to existing nets by selecting wires without off page connectors and going to the same menu (again this can be done for multiple at a time)

My only complaint is that there is no bi-directional off page option (there is one for ports...not sure why not for off pages)

Update:
I upgraded my OrCAD to 17.2 and lost this feature. I learned this is actually an app that I had installed from EDA. The app is free on the OrCAD Marketplace and is called CoolEditBox. On the market place there are a lot of comments that the app is incompatible. I emailed my EMA-EDA support and they gave me a link to one that works. Maybe they'll update the app soon if they haven't already.
