Querying multi-value variable while appending it to other variable

I have two variables, $node and $port that I want to append to each other in a multi-value query. $node is a multi-value variable and port is a single-value variable.

What is expected: This is with the ip’s manually typed in and all three ip’s are show on the graph:

What happens when you put the variables in: only one ip is graphed instead of the expected three:

If this is not possible, I am also okay with putting the string “:9100” at the end of $node and not using the variable $port

This is grafana v6.7.1
