Several footers in report

Leo Bidi

Hi, I need to print several memos ( more than 10 ) in a footer but depending on some conditions , I need to make some invisibles and then cut out the lenght of the footer to save paper ( 80 mm printer ).

Is there a way to "group" some memos in differents footers so if condition , only need to make the footer invisible and not all the memos one by one ?

Thanks
