Can MS Deploy do a package and transform, but not deploy?

Using msbuild in .NET 4.0, I can build web project with the "Package" target, and it does a nice job of putting the package in a zip file. But, when I look at the web.config in there, it's not transformed, it has "$(ReplacableToken_Web_SiteConnection-Web.config Connection String_0)"

I can run the "TransformWebConfig" target and it will do the proper transform, but just in its own silo.

I can also run the "Build" target and pass the "DeployOnBuild=True;DeployTarget=MSDeployPublish" properties and it will deploy the package on my server with the proper web.config transform done.

But, if I want to manually deploy the package to the server, how do I do a "Package" with a "TransformWebConfig" so that the zip file has the final web.config in there?
