Modify MouseOrbit script to snap to specific view on button click

Hi,

I'm using a c# script called "MouseOrbitImproved" (courtesy of Veli V) to rotate around an object in my scene (see code below). I would like to add buttons to the UI that allow the user to select specific views (Top, Bottom, Front, Back, Left Right). I've played around with changing the cameras location based on clicking a UI button, but the camera does not respond. I'm guessing the nature of the "MouseOrbitImproved" script overrides any changes I make programmatically. Any ideas on how I can achieve this goal while still using the "MouseOrbitImproved" script? FYI, I'm a novice coder so please be gentle ;)

Thanks in advance for any help/advice.
