As long as what you are doing is linking and not actually embedding the attachments, you can get what you appear to want by putting a file URL in the notes field. If your username is joeschmoe, and the file is world_domination_plans.pdf on your Desktop, the URL would be:

file:///Users/joeschmoe/Desktop/world_domination_plans.pdf

(yes, 3 '/' characters after "file:")

If you don't like typing and it is a file that Safari can open, you can open the file in Safari and drag the URL from Safari into the notes field.

You'll just get the link, no icon of any sort.
