Already implemented in v1.3.1, see route attribute krt_prefsrc in:

BTW, in this case the problem is in the dns-server - properly implemented
UDP server should answer from the same address the request was sent to,
without any tricks with route src attributes.

Another way (simpler and more usual) to fix that is to configure
dns-server to bind to the only one IP address. Most servers have some
config option to do that.
