DiskXtender and Different Retention periods

I need to put data for different customers onto a Centera via DiskXtender. Each file could belong to different company, with different Retention requirements.

Can I get DiskXtender to connect to multiple Pools on a Centera, or configure it to work with Classes (for retention) on the Centera ?

If I can only configure a single Pool and it does not support Classes, then this application will not work for me.

Thanks
