I have not dealt much with multicat myself. AFAIK, at present you can't.
But I can't see any real reasons why not.

The multicast reduces bandwidth for ICP requests going out, but once a
reply comes in it still needs to be linked to a sibling peer.

At this point some experimenting (or advice from Henrik maybe) is needed
to follow it further. The linking I think looks up an explicitly configured
peer based on the replying source IP. It may be useful to make the peer
dynamic if sufficient security protection can be added.
