Multiple interfaces for site-to-site VPN on ASA

Is it possible to segment site-to-site VPN traffic to different output interfaces on the ASA platform.  I would like to direct site-to-site VPNs from partners to a different interface than site-to-site VPNs from corporate sites.

On an ASA, you can only have one default route ( going to a single interface, but you should be able to use the other interfaces for VPN connections.

For example:

Interface  outside1      IP Address: with default gateway of

Interface  outside2      IP Address: with default gateway of

You would have your normal default route of route outside1 and you would point your corporate VPN tunnels to the endpoint peer address of

You would then have routes for your partner sites going out interface outside2.  For example, a partner with IP of you would:  route outside2

Point the partner VPN endpoints to build a tunnel to your external address of

Make sense?
