[opensuse-factory] What's the best alternative to Multisystem?

Unfortunately, the Multisystem program that allows one to easily create a USB drive with multiple live-ISO images can only be installed on Debian-based systems. http://liveusb.info/dotclear/index.php?pages/install Is there an alternative for rpm-based systems anyone can recommend that also allows one to easily install and run multiple ISOs on a USB drive?
