Concatenate more than 2 tables

I have successfully concatenated two datasets by linking them to the Concaenate node.  What do I do when I want to concatenate more than 2 tables together, as there is only palces for 2 links to the concatenate node?

There is also the Concatenat (Optional in) node, which takes upto 4 tables


and if you need more than 4 you can daisy chain them together. If they are seperate files in the same directory you can also make a loop to read them in.
