VS.Net - automating "Execute Custom Tool"

My organization has a visual studio (2008) project that contains a slew of Crystal Reports. One thing we'd like to do is have the ability to automate the build of this assembly, especially when either 1) a new report is added to the project, or 2) whenever one of the existing reports is modified.

Everything as far as updating the p开发者_高级运维roject with new or modified reports is all fine-and-good, but we have yet to figure out a way to run the "Execute Custom Tool" against them (to regenerate the wrapper classes around the reports). Do any of you fine gentlefolk know of a way to do this?

Set up a build server for Continous Integration. Use either TeamCity from JetBrains or CruiseControl.NET if you're not drinking the MS TFS Kool-Aid.
