In some scenarios, it would be helpful to have the path to the report available, for example, as a Global Object, so that you may use it in the Expressions.

Here is a use case. The PictureBox resolves relative paths with respect to the report's folder. Currently, if you want to check whether an image that is in the report's folder exists by its name only, you need a custom user function. If you know the report's folder, you may do this with System functions.
