Colour Labels are Volatile across projects

Used to be youd lose your logging info if you did a match frame.
Thankfuly that's changed with FCP4 and Master clips.

unfortunately there is a logging catagory that is still volatile:
Colour Labels.

Label a Clip.
Copy it to another project.
Cut into Timeline.

now, all is fine up til this next step:

Matchfframe, and cut back into the timeline.

The colour Label is gone!
No Colour!

As I said in the previous post, this is a problem with anyone working with multiple projects.
