I am just saying, that the solution I was originally seeking for should follow the constraints I stated - e.g. we should be able to do so using 'MODIFY REPORT' command in run-time. Nothing else is allowed and offering other ideas which do not follow these constraints is not helping me with that particular problem I stated.
