Build only changed projects in Visual Studio solution

Hello,

I have a Visual Studio solution file with multiple projects inside, which I think is a pretty common setup.

Each project is a console application that I would like to deploy separately. Each project has an independent deployment step in teamcity. Is there a way to trigger a step for the project only if files in it has changed in git? Right now I don't see a way to do this, I have to deploy all the projects on any change in git.
