Notification Centre on WP8.1

I just want to know if you can setup custom notifications PER EMAIL. WP works for phone and texting, but for the love of God, I don't know why they stopped there and didn't give the option for emails. This is critical for me and getting to the point where if it doesn't happen, I will have to look at another OS (I know people don't care, but it is a feature I have been waiting for since WP7).

Anyone know if this will be allowed in the WP8.1 release?
