JMeter CSV data set split into threads (users)

What I want to do:

I would like to test behavior of the system for 50 users. Each user has to do the same action X times, with different input ( X - depends on how many records I have in the CSV file, so if the file contains 1000 records, each user will do the action 20 times).

What I actually did to do that:

I set up CSV Data Set Config (with CSV file with 1000 lines) and ofc set up Number of Threads to 50

What is my problem:

Now I'm quite not sure how to share the CSV file so that all user will have unique poll of the lines from the file. (so each user will have his unique lines from the CSV)

What can I do to workaround:

I can copy thread groups to make 50 thread groups, and add them separated CSV files, but it sounds ridiculous...
