[support] Use backreference as argument in block view?

Hello All, I'm using this solution to limit a block view to nodes referenced to the current node: Add the node_refence as argument Set "Action to take if argument is not present:" to "Provide default argument" Set "Default argument type:" to "Node ID from URL" Now i want to do the same when viewing on of the nodes out of that view/list, but the other way around, using the backreference... How would i go about that? Best, Toon
