It should be in relation-file:

type=destination_sign { apply role=to { set 
foobar:destination=='$(foobar:destination),${destination}' | 
'${destination}' } }

Now every to-way is tagged with destination-Tags of all relations 
seperated by ,

In lines-file you would need something like:

highway!=*_link { delete foobar:destination }

Maybe you would like to merge foobar:destination with an existing 
desination, but I don't know if this is a good idea.
