Is there an easy way to make changes when simulation is running?

Hi everyone,

When I create a new simulation job I see my nodes are working and doing their jobs. But then I wanna change a little part of the code or add a new node. After that here the steps I watch:

• Close the simulation.
• Do the changes or add some new features on Cloud9.
• Build, bundle and copy your code into S3.
• Run a new simulation.
  Do I have to repeat these steps all the time when I want to change something? I am wondering that is there an easy way to do these or not?

Thank you.
