Backup .BAT file questions

I recently created a backup batch file for my mom. The file copies (xcopy) her files to an external drive. It looks like this:

Code:

xcopy /e /d /v /q /y "C:\Documents and Settings\Owner\My Documents\My Scans" "K:\Scans"
xcopy /e /d /v /q /y "C:\Documents and Settings\Owner\My Documents\My Pictures\MOM'S PICS" "K:\Moms Pics"
xcopy /e /d /v /q /y "C:\Documents and Settings\Owner\My Documents\My Music" "K:\Music"
xcopy /e /d /v /q /y "C:\Documents and Settings\Sarah\My Documents" "K:\Sarah"
xcopy /e /d /v /q /y /i "C:\National Pastime" "K:\National Pastime"

I set it to run every night at midnight, and set a cool web 2.0 type desktop icon, so she could run it at will.

Manually editing the file works fine, I guess, until I go back to school. But what I'd really like is the ability to right click on a file or folder and have an option to add it to the backup list.

Can anyone think of a way to do this?
