Use bullnose to leave curved fillet at bottom of pocket

I would like to leave a curved filet on the bottom contour of a pocket with a 3/8 bullnose end mill. The remainder of the pocket would be milled out by 3/8 end mill. I am using a counter operation followed by a 2d pocket with a flat bottom endmill. The second operation clears the bullnose operation. How can you offset the pocket operation to clear the remainder of the 2d pocket and not remove the fillet?

Axial stock to leave and radial stock to leave should work for you but can you share your file?

I was trying those two parameters but was getting an about the z axis height. I figured out now I believe that was because of how shallow the pocket it is. If I set Axial stock to leave to 0 and Radial stock to leave to half of by bullnose end mill diameter, it works as intended. 


I've attached an example file with it fixed.
