Can i have a variable parameter in csv Data set configer in jmeter

This is my test plan where the first CVS data set configure is like

And the Second CSV data Set configure is like

I want to read a file that contains all the file names and go inside each file and read each line and form a http request and hit the server. I don't want to use loop controller because i need concurrency in terms of requests in a single file.

Say the file1.csv contains 10 lines which is equals to 10 http calls and i have 5 threads then the threads have to handle the 10 calls concurrently
