Trigger build when a label is gerrit is set

Hi,

I have a requiremnt where I need to trigger a teamcity build only when a patch is submitted in gerrit and its label "Build-Queue" is set to +1.

I have these labels in gerrit -

Build-Queue   +1  triggers a new build)
Verified           +1 if build succeeds else -1)


Is there a way to do this by setting VCS trigger->VCS rules in teamcity?

thanks
