[Dnsmasq-discuss] tags and duplicate options

I am trying to set the MTU for a specific host.  I tag the host with the 
vpnmtu tag and then later I have the following in my dnsmasq.conf file:

dhcp-option-force=tag:vpnmtu,26,1407
dhcp-option-force=26,1492

This means that the second dhcp-option is ignored (and yes, I understand 
this is documented.)  But what I have not been able to find is how to 
tell dnsmasq to send one option to a tagged host and another to all 
untagged hosts.
