Suppress Groups in Reports

[vsteinly]

I have a financial report that I have three levels of grouping for monthly expenses. Depending on how the transaction was created it can have some of the groups that contain no data. So here is are my groups

Account - will always contain data
Operating Unit - will not always contain data
ABC - will not always contain data

I'm looking for a way to suppress the groups labels when there is no data. I have looked at the "Can Shrink" and doesn't do anything.

Any suggestions?
