Can you use two workflows on one project?

Question

We have an existing workflow for the current project. We added the sub-tasks to this project and we created a sub task workflow.

My question is can I just associate the new sub-task workflow to the project and keep the existing workflow for the project tickets? Or do I need to create a whole new workflow that is comprehensive?

Yes, that is why you have the workflow schemes.
