Subnet for wake on lan with network binding

Is it correct that I cannot specify a subnet when sending a WOL packet with the network binding or am I missing something here?

I want to wake my LG TV which resides in a different subnet but both the webOS and the network binding don’t allow me to specify a subnet. I use the exec binding now to perform this operation which works great, but I was wondering if this really cannot be done with the network binding since the v1 WOL binding seemed to have this feature built-in.
