Am I able to create multiple segments at one time?

I have a use-case where I know that I'll need to have close to 600 different segments, and I want to add contacts to these segments as their CDOs are created through the API.  I'm not able to find any documentation on how to create these segments all at once...all I can track down is how to create segments one at a time.  I can do it this way - but it'll take me a long while to do it. 

Any suggestions??
