command line parameter to run directly from cdrom?

Does anyone know how to start my original psx cdrom from command line using ePSXe. The idea is that I have a shortcut to run whatever cdrom I put in the drive without having to use File->Run CDROM. I havwe a lot of PS1 games and I don't really want to try to rip them all to my hdd. So far I only found -loadbin to run a specified iso. Of course, that doesn't help me in my situation.

Thanks,
Morothar
