OmniPlan for Scientific Article Writing

I am a Professor and a devoted user of OmniFocus that runs my life.
I write/publish around 10 articles per year and each one of them has many steps from data analysis, writing, formatting, submitting to journal for review, responding to reviewers comments… So, I always try to keep track where each paper is, who is working on, what is next step while tracking tasks, students, reviewers and publishers.
I downloaded the trial version of Omniplan and I am not sure what is the best way to make it work. I use one Project/file all my articles in progress. Each article is one task and then all the tasks of each article are in subtasks.
This way I can see in the diagram where all the articles that I am working. Any suggestions are welcomed.
