TeamCity Message for dotCover Report File

Is there a way to emit a message from a build runner to specify the location of a dotCover report file similar to what you can achieve with a TRX file and a message? The link http://confluence.jetbrains.net/display/TCD6/Manually+Configuring+Reporting+Coverage does not indicate that this is possible. The link http://confluence.jetbrains.net/display/TCD6/JetBrains+dotCover indicates that you can just add a build step for dotCover, but what if I want to integrate this into an existing build script I have? Thanks!
