Reset button for radial blur

I frequently use the radial blur tool in PS and would love to see a reset button on the tool (similar to that on the curves tool etc.). This is because, when I have moved the centre point of the blur for one image, if I then open another image to apply a different radial blur, I have to close the whole app to get the middle of the blur to be at the centre of the image, and that is a big waste of time. 

Better yet, a button on the tool that allows the user to place the centre of the effect directly on the image in the workspace (similar to how the eyedropper tool can pick locations on an image). This kind of adaption would allow multiple repositioning attempts and take away the guesswork when moving the centre in the box on the pop-up window for the tool.
