distinguishing subdomains graphically (e.g. plotting subdomain-labels) in Comsol 4?

Hi,
in Comsol 3.x it was possible to examine the subdomains via showing the subdomain-numbers in geomplot using the option 'sublabels','on'.
Is there a possibility in Comsol 4 to distinguish the subdomains graphically like showing subdomain-numbers (or coloring a certain subdomain) in a plot?
Thank you in advance
