Reading ProjectSuite name

I need to read the name of the current project suite in order to define where to save test run data.  This is for a Manual test project; I am defining an OnStartTest event to capture user information.  As the event will be used in multiple projects I want to be able to read the current name rather than having to upate the location manually each time a new project suite is made.  I've explored the ProjectSuiteFileName property but am unclear from the given example how to read this without first having to define the project suite name manually.
