[pstricks] Request for a psgraph option

I find psgraph very flexible for the large number of same size graphs  
I have to create, with differing x and y scales. I am preparing a  
document for a publisher where about half of the graphs will need to  
be printed with a gray-scale grid. setgrid called after psgraph draws  
the grid on top of the axes drawn by psgraph.

The following modification to pstrocks-add works as I need it.

\use at par%
\setgrid(!#3 ceiling #4 ceiling)(!#5 floor #6 floor) <--- Added

I am not skilled enough to know what I should do to add an option that  
would allow me to switch the grid on when I need it. Any help is
