Yes, you can create multiple pipelines!
Go to "Settings" > "Configure pipelines" and click on the large orange "+" button at the bottom right of the screen (it might be behind the chat window) to reveal two "Create" options.
Click on "Create pipeline" to create a new pipeline.
Afterwards, click the "+" button again to add the stages you need. You can also reorder stages by dragging and dropping, or edit them by hitting the pencil icon.
