You mean from the in- to the outside or vice versa? You want outgoing traffic to be natted to multiple publics?
Could you elaborate?

Well, you can't NAT one public address to multiple private addresses. You can forward ports on a single public address to multiple private addresses though. If that's what you're looking for then use:
static (inside,outside) tcp outside_ip port_number inside_ip port_number netmask

So, for example forward WWW to one host and RDP to another:

static (inside,outside) tcp 80 80 netmask
static (inside,outside) tcp 3389 3389 netmask

You're welcome. Don't forget to open the ports for the public address in the access-list as well :)
