Jmeter_Passing differnet account numbers from parameters file in single request

How to pass several values in a single request, if I have 20 account numbers, we must pass 5 distinct numbers each time in single iteration, For EX my script (single request) has 5 calls and we need to pass 5 different account numbers each time from single request (post method),

Accnum:- 2123 5678 9890 6780 8899 9990 7651 8976 Example:-

call 1: - 2123 call 2: - 9890 call 3: - 5678 so on...

I tried adding 5 csv files, but it will be time consuming, so I wanted to use formula.
