Change desktop excel icon

I was wondering how I could change my desktop icon for one specific workbook to something other than the excel icon. I saw the below link (2nd tip) but that changes the icon for every file of a specific file type. I just want to change one specific file's icon on my desktop to something custom, like a clipart picture of my choosing. I also know that this can be done with shortcuts, but I need it to be changed on the original file. I tried using the IconChanger program, but the icon stayed with the file name so if I did a "save as" or emailed the file, it disappeared. I want it to stick with that file for good, or any file I duplicate from the original, and work on other computers as well. Thanks!
