Relative References in VB Macros

I want to use the macro writer to write a little program that inserts the current date behind a cell, as a comment. I can record the macro, no problem (It even picks up the Ctrl-semicolin shortcut for the date), but I can't get it to run in any other cell but the one I created the macro in.

I know the solution is to use relative references, but the little checkbox to do this (when creating the macro) is gone. So, how do I modify the macro to use relative references? And why in heavens did they remove that check box!?

Thanks in advance for the help.
