I'm grouping sales numbers, and I want to do something like determine whether a number is 0-50K, 50k-99k, or 100k+. I know I could do a custom group to handle that on the detail level.

The challenge is that I want to custom group other groups. On the detail level, I have each individual sale. Those detailed records are grouped by customer, and that group has a sum of all the sales. What I want to do is group each customer into one of my 3 categories. So I'd be using the group sum number as my qualifier for which group they go in, which Crystal doesn't want to let me do.

Any good way to accomplish this?
