working directory on startup?

Hello,

I would like to startup CP 3.0/4.0 and automatically be in a specific working directory drive instead of C:\Prostart (We currently do not use a PDM server). I can't find any setting in my config that drives the current location to C:\Prostart.

Does anyone know of a setting in config that will allow this?  Just FYI, I know that you can set it manually by right-clicking.

Thank you!
