Better Devotional Customization

I love themeing my days with reading the poetic books of the Bible on Sundays, the law on Mondays, the Epistles on Tuesdays, History on Wednesdays, the Gospels on Thursdays, the Major Prophets on Fridays, and Minor with Revelations on Saturdays.

However, I always restart one grouped theme before another and would like to find some balance to finish together by making the nessesary adjustments. If this were possible to somehow make it "theme friendly" this would make the best devotional creation tool even better!
