YouTube – can I see anywhere which video has brought in new subscribers in the last 24 hours?

Is there anywhere I can find out exactly where the last 10 subscribers on YouTube came from?

I usually get about 10 subscribers overnight. I'd like to know which video(s) brought them in that night. I upload a video every evening and see that it wasn't the most recent one (in the analytics for this video, the subscribers are usually "-"). The other videos already have a number listed, for example, "+9" – is there an overview of exactly how many were added on which day and where?
