Hello @Gavin_Mountford,
There are different ways you can set this up. Instead of a section called “show episodes” I’d rather use the sections to display the stage the podcast planning is in which could be the Idea stage, planning, scheduled, post-production work or similar and then you can move the tasks with subtasks along. You can use Task templates in order to create new tasks per podcast.
Or depending on how much work you do per podcast you might even consider creating a separate project per podcast, then instead of the subtasks you have actual tasks. But that is probably more recommended when you have a lot of work to be done per podcast and different people involved. As then you could also use the Portfolio view to have a top-level overview.
You can also find some templates on Templana.
And I have also found a template from Marquis.
I hope that helps.
