Generate 'Random number' variables in JMeter

Is it possible to generate 'Random number' variables in JMeter?

1. I have recorded a user journey
2. I have imported the journey into JMeter
3. I have to type in a unique 4digit id within my user journey test case
4. Its default to 2323 at the moment in jmeter

Is there a way of generating a random 4didgit number? For example thread1: ID: 2323 thread2: 3334 thread3: 5643
