Concatenate (Optional in)

I would like to concatenate 5 different results, but the Concatenate (Optional in) node only has a maximum of 4 inputs.  Is there another way to do this using just one node?  In future it would be nice if the Concatenate (Optional in) node could be configured to handle 1-n amounts of inputs.

That's correct, the Concatenate (Optional-In) has 4 in-ports, if you need to concatenate more data branches, you have to work around with 2 or even more nodes. To clean up the workflow, you might want to encapsulate those into a meta node. The number of nodes is hardcoded within the implementation and can only be changed either there or while Re-configuring the meta node itself. Sorry, that's the way to go.
