Ability to magnify image while refine mask tool is engaged

If you click on Refine Mask, but you forgot to magnify your image to 100 percent (or whatever magnification is desired) then you now have to cancel the refine mask process, enlarge the image and then go back into refine mask. But if you don't like the magnification you chose, then you need to cancel again and then resize the image and then go back to the refine mask process..... Allowing magnification while Refine Mask process is engaged would save a lot of time...
