maximum limit of 20 derived fields

Just to pile on some since you discuss limits, I have put in feedback, yes generic sounding, but specific to the entire QB program.  There are way too many QB imposed limits that don't need to be there.  Please follow this User Feedback link and vote to try and get QB to remove all the arbitrary limits they have imposed.

Thanks.
