Analytics - Post performances timeline

Idea

When I check the details of a post from the past, I'd like to see the KPIs evolution over time.

that helps to see how the reach evolved in the first 30min vs the first 2 hours and correlate that to the engagements metrics. 
That will help to understand better what the posts that generate the best performances ( whatever the KPIs you are following) on a similar time frame are.

Today, the problem is that if I make a post and check the engagement after 2 hours, I have no idea how it's doing compared to my post from 2 weeks ago.
