Wouldn’t Simplisafe want to have less video storage?

Am I missing something? I like others would like the ability to control when the outdoor cameras record and notify. Not an all or nothing solution. This would of course mean less drive space needed for Simplisafe. To a novice this doesn’t seem that difficult and would save Simplisafe money. My concern is that maybe it is not possible with the current Simplisafe ecosystem and that is why it hasn’t been done yet. Do we need to wait for SS4? Any thoughts?
