You could specify a Range of cells - for example $AA$1:$AC$1000 and put that
range in another cell like Z1. Then in a macro you could copy whatever cells
you need and paste in the range defined in cell Z1. You can also check out
the "Indirect" function or "Index" function. I'm not sure exactly what
you're trying to do, but it is likely that you can do it with macros or those
functions.
