Question: feature request (Code Generation) fortran and matlab

Hello.  The ‘optimization’ flag for the fortran codegen or CodeGeneration only will operate on a single array.   It would be very very helpful to me if I could put multiple arrays (all of them having common variables) as input that the codgen and CodeGeneration can automate all at once (im mostly interested in the fortran and matlab codes).  What I do now as a work around is manually put all the multiple arrays into one giant array, then run code gen, then on the fortran side later I have to manually recopy the giant array back into the original smaller arrays.  maybe there is a better workaround, does anyone know of one?   If not id like to make a feature request if possible, not sure how to formally do that.  Thanks!  Ryan
