Changing File Name Fonts

How can I change the font of individual file in the lister? i would like to be able to keeep the copy I am working on in a different color than the originl copy of the file.
The rename fuction lets me specify the case, but nothing else.

You can use labels within Opus to change the color of a file's name, or make it bold or italic.

Note that some editing software will clear labels when you save new versions of files.
