WHD Reporting Limit for Pie Slice Catagory

When we enter in criteria for Pie slice catagory we have found it most annoying that it will give the top 4 or 5 slices and then lump all other catagories in to an "Other" slice.

We have tried to get it to report all of the slices but the most it can do is 31..? That seems to be an odd number to me.  Is there anywhere that we can raise that limit or even have it show all?

Thanks
