An option to ensure that certain subreddits always appear on the front page.

I’d like to be able to control which of my subreddits always appear on my front page. I’m well over the 50 subreddit maximum, and I enjoy how my front page is different from day to day with the random inclusions. But there are some subreddits that I would like to always appear on the front page, and others that seeing once in a while is just fine. For instance, I’d like r/fitness posts to always be present, while r/apathy and r/woahdude can duke it out over which one makes the cut.
