Hole wizard custom sizing

I was showing a fellow engineer how to use hole wizard for the first time and found something that I had not noticed before.

In the custom sizing fields, you cannot do math functions. for instance I wish to add .015 to a standard counter bore dimension. I cannot just type in + .015 as I would if I were changing an extrusion.

Has this always been this way? I can recall using custom sizing but not a math function in the command.

This looks like a bug to me.

I am using 2011 sp4 I do not have maintenance.
