Custom calendar tracks for Sermon Manager

It would be great if we could add a track that includes some of our own major church events we may schedule sermons around!

yes

@Phil Gons (Faithlife)  , if I understood correctly , this idea is the same as this one:  https://feedback.faithlife.com/boards/logos-desktop-app/posts/share-an-entire-calendar-with-your-sermons-in-sermon-manager-to-a-group 
But if not, I think it can be combined into one bigger idea.

I would even like to have a school year option (September-August)

YES! Being able to show a calendar of our own parish events would be wonderful.
