Retain folder location when you open a project (separately from file open)

Right now all of the open dialogs go to the last path used. It would be cool if the open project dialog stayed on the path where you store your project files. Basically store one last used location for file open and one for open project. Or this could be solved by adding a setting for project files location for easy project switching. Maybe this already exists in the settings and I don't know about it?
