Integrating Editorial Calendar with Projects

We are thinking of using the editorial calendar for the first time, I’m wondering best practices to use it to integrate with projects, for instance. Nov theme month is drop out prevention month - we want to decide what editorial/pr/comm actions to take to support that (SM, PR, Op-eds, Speaking engagements, etc) … we want to throw out ideas and then task them accordingly, but there is also then the step by step actions for the calendar (i.e. draft an article, edit, approve, print) . But in other projects for our team there are events/items/tasks already listed, i.e. conferences during that month, product launch, etc. Ideas?
