3D viewport / Ortho and Perspective question

Is there a way to force the numpad shortcuts to switch to ortho view while being in perspective view? Like if I’m looking at my model in perspective view than press 1 on the numpad it’ll switch to front ortho, than simply rotating the view will move it back to user perspective.

I recently updated Blender and I was able to do this in the older version I used, but now I can’t. I understand that I can just press 5 on the numpad to switch between ortho and perspective, but I’ve grown a little too used to the previous way and would like to somehow set it back.

User Preferences->Interface->Auto Perspective

That was it! Thank you very much!
