Certainly you can do command line editing with grub during boot ( the
'e' key ).
However, those edits are only in memory and only during that boot.  Grub
cannot write to a filesystem that is not even mounted yet.

To make changes permanent you need to actually edit the text file
grub.conf and save those changes when the system is running.

Also, How are you going to test your saved changes if you do not reboot
and let grub read and use the changed configuration?
