can I colour folders in left-hand column of DT?

Quick question:  can I add colour to any of the folders in the left-hand column of DT?  I’d like to be able to do that, just to help me identify one from another at a glance.
Thanks in advance for any advice!

Labels ("Colours") will be part of version 1.9 (should be available in Q2/04, next things to come are DT 1.8.1a, a minor bug fix release, an DT Pro in April).
