Is it possible to enable NetBIOS queries on all IP addresses of an adapter?

By default Windows only broadcasts NetBIOS queries on primary IP address, if
multiple are configured on the same interface. I would like to access PC by
their names irrespective of their primary IP address, as long as they are on
one of my subnets.
There is an optional BroadcastAddress entry in registry under NetBT, but
address is valid for all subnets.

Thanks.
