Can’t you use lists and make a “multiplex” node? It will be with cables, but it should be a “cleaner” option for now. Make a new node with an “add to list” node, publish as many inputs you need/want, and publish the list output. Then make a deplex node to pick out the values and insert it in the nodes you need the data.
(I get the idea by the way, Reaktor Core uses something like that and it is convenient).
