Hi there,
This is a great suggestion. We do offer a number of lessons that focus on strum patterns. Some of them are in Guitar fundamentals 1, like this one: https://www.guitartricks.com/lesson.php?input=23535&s_id=1914
It's a good idea to have a dedicated lesson within the Core Learning focused on strum patterns, and so I'll pass that along to the team.
With that being said, strum patterns are pretty specific to a song, so I believe that most people learn strum patterns by learning songs, which you said you have done as well.
Learning a strum pattern also has a lot to do with your ear, in that most of the time you will be able to hear the rhythm or pulse of the guitar.
Anyway, thanks for the suggestion!
Billy
