Can a cosmetic sketch be converted into a standard sketch?

Can a cosmetic sketch be converted into a standard sketch?
We are converting from one system to Creo 2.0.  We have labels with signal words,diagrams and descriptions.  We need to be able to color backgrounds, the diagrams and block lettering the appropriate colors.  For example the signal word "Caution" needs to be black with a yellow background.  The signal word "Warning" needs to be red with a white background and so on.  There are also some diagrams and additional information on the labels that need to be colored as well.  The designer doing the conversion created all these items using cosmetic sketch which was time consuming.  So if these words and diagrams can be colored filled using the cosmetic sketch, we are not aware of how this is done.  If it can't be, then using extrude and coloring the surfaces would need to be done.  But of course a cosmetic sketch cannot be used for features.  Recreating the labeling sketches is not desirable because of time.  Does anyone have a solution?
