Same client, different IPs?

Greetings!

I have setup and installed OpenVPN and can connect to it just fine. I'm trying to figure out if there's a way I can have the same VPN user logged in multiple times, with each user getting a new IP from the pool.

I currently have a single client which has the default address pool, but also an assigned virtual address. I would like for the client to *not* have a specific assigned address, but rather be assigned the next available IP from the pool in which it is a member.

Is this possible?

Thanks in advance,
Jay
