How to adapt page margins for odd and even pages

[_Manhattan]

Hello,

I want to adapt the page margins of my pdf report in dependency of the odd/even pagenumbers. Till now, I have tried to work with the "leftmargin" etc. options in ods pdf and the ods layout gridded statements. One of the problems I have encountered is that the page numbers are affected by the margin options as well which is not something I want. It would be fine though, if the page numbers are printed at the bottom left/right part of the page according to the odd/even page numbers. Could you help me to achieve the desired result? My code looks like this:

proc datasets lib=work nolist; delete sample_data input_data mean: VariableInfo freq: ;run ;quit;
