[AccessD] Evaluating report's formulas from table

<Cross posted AccessD and Accessl-L>
Dear All,
I have zillions of formulas clustered in groups of <=10. So, if I make report for every group I need a lot of reports. My intention is to save the labels and formulas in table and to evaluate them "on the fly". 
Are there any clues, hints for me?
Many TIA's,    
Ervin
