Jmeter-Is this possible to change the processing order

I am using j meter tool.I have to do three process and do the load testing for the same.

1. Login
2. Add Patient(After login)
3. Logout.

When i run the j meter for 100 users. It will executed in the following way

1. Login(100 users) is executed fully.

Then only Add patient process is executed.Now my doubt is how to execute in the below order

1. Login(1),Add Patient(1),Logout(1)
2. Login(2),Add Patient(2),Logout(2) etc.
