Variable Loop End (2 ports)

I was just wondering why this isn't a thing?

At the minute I have this workflow:
 

List Files --> Table Row To Variable Loop Start --> CSV Reader --> Row Splitter --> CSV Writer x2


I would want to move onto the next loop after both files have been written out to, however I'm not sure how to do this.

Answering my own question:
 

You can attach a flow variable to the top of the variable loop end and it will still wait for the second csv writer to finish before moving to the next loop.

or use the merge variable node inbetween.
