I'm not sure how much this will help but, I actually have a hard copy of
a Bob Marley song book. It has strum patterns in the back of the book. They are numbered say 1-10. Then under each song it has a suggested strum pattern.
Though most of my song books like "greatest hits of the 70's" do not.
So, at least some have thought about your plight. And it really is helpful.
It is a shame others haven't picked up on the idea.
