Project path or other macro in command-line parameters for console project in VS2010

The debug tab of the project properties for a console application in VS2010 allows me to set command-line parameters to pass to the project whilst debugging.

I would like to set a parameter which is a path and the path is specific to each developer/machine, as it is a path which resides in the solution folder and each environment is different.

For pre- and post-build events, I can use macros such as $(ProjectDir), but I can't find a way to do this for command-line parameters - is there a way? A hack is fine, as long as it's not too awful!

Thanks
