Adjusting element widths easily

I have both Pitstop 7 and Pitstop 8 on different computers. When trying to simply adjust the width of a fill box it seems you have to adjust by changing the top left, size, top right coordinates in the inspector pallet. Is there an easier way to do this or can newer versions of Pitstop accomplish this in a similar fashion to Illustrator in Indesign where you just set the reference point and adjust the height or width or just direct select the 2 endpoints and arrow key to the correct position? Accomplishing this in the inspector is painful and many times I end us just outlining the fonts and fixing in Illustrator.

Thanks
