How to force the sublime for each build to use the same terminal window?

Question

Building projects

Here is a build that launches a Nodejs application in a separate terminal, and not in the sublime console.

{
  "cmd": ["gnome-terminal --profile sublime --command='npm start'"],
  "working_dir": "${project_path}",
  "shell": true,
}

How can I run each subsequent build in the same terminal window? (A bash-level solution is fine too) The
alternative is to run a rebuild.
