Yes, but setting the interface also affects the source IP address, which
is where I've used it--for example, testing IPSEC tunnels. I cannot say
why the original posted wanted the feature; the answer from several of

use routing tables" and my response was that it is in fact possible.
Practical or easy, I do not know.
