I had considered adding the feature. From the development angle, it's the kind of thing I'd have fun building. I'm a big fan of automating tedious/repetitive/boring tasks, or just things I would tend to forget. And from a user perspective, it's something I would take advantage of too.
But I don't know how I would communicate the addition of the feature without making it sound like I'm asking for money. So the anxiety of that situation is the reason I haven't added anything like that. I think I will now, and blame @Catherine for its implementation
