Opening IDEA 9.0 directly to a specific project

Hi,

I am not using the .ipr files anymore but rather the .idea folder structure. I would like to be able to open IDEA to a specific project. At the moment it seems to open the last project opened. I can no longer find the setting "Reopen last project on startup" (Settings -> General -> General Options) in version 9.0. Also I would like not to switch to using .ipr files which seemed to allow me to open that specific project. Is there a way to add to the shortcut a -project argument or something along these lines? Opening one project just to get to another is time consuming.

Thanks,

Louis
