I was able to do just what you said by using unetbootin.

http://unetbootin.sourceforge.net/

I first downloaded the Scientific Linux DVD, and use unetbootin to install the 
first DVD.  This get's the USB stick bootable, and you can use it for that DVD.

But, you can then load other releases onto the USB stick, into their own 
directory, and then change the configuration file so they come up as an option.

I have since wiped the USB stick and put other things on it, so I don't have 
all the details.  But it was pretty handy.

Anyway, unetbootin is a good place to start to do that.

p.s. Oh ... actually doing the DVD install, as opposed to the network install, 
required some extra tweeking because the installer was looking for ISO images, 
but I just put the iso images into their own directory, and everything was fine.
