No.  Currently that is not possible in OpenVPN.  Some of the core
developers are looking into resolving this, but it has turned out to be
quite hard to resolve and fix properly.  So this is still being worked
on, but we have no ETA for this.

What most users do is to listen to all interfaces and only open up the
port in the firewalling.  Some have chosen a different path using NAT to
forward packets from one IP/interface to the one OpenVPN is listening
too.  But some have needed to also add --multihome in the OpenVPN to
make this work.

For most of our OpenVPN users, only open up the OpenVPN port on specific
interfaces/IP addresses in the firewall is more than good enough from a
security perspective, and really simple to achieve without too much
troubles.  But YMMV.
