I don't understand exactly what you mean by "perspective function of crop".
PSE can correct for lens distortion, including perspective correction.
I suggest that you install the trial version of PSE -- you'll have 30 days to see if it can do what you need.
By 'perspective function of crop' I mean can you take the 4 corners of a photo that may have been taken on a bit of an angle and square it up to look correct on the screen. Can elements 10 do that or somthing close?
It can do "something close" -- you move the sliders for vertical and horizontal perspective independently to bring the image into alignment with a supplied rectangular reference grid.
I use a free plugin that works more like what you describe -- place the 4 corners of a reference rectangle on the points of the image that should be a rectangle.
