Feature Request: "Event" metric

[bkuhl]

I love the addition of Table Metrics, thank you. One way we'd like to use tables is to be able to generate an "Event" metric so to speak (why is naming so hard). The idea being it'll list the last X of a given resource meeting a criteria. Could be the largest customers who signed up, the most active of a given resource, etc. Here's how this looks on our dashboard outside of nova to better communicate the idea:

In this case it's showing Discord servers. We list a number we're interested in (head count within the Discord server), the avatar (for visual flare) and the server name and whether they've gone paid or not.

I was thinking "Event" might be ok naming since it seems like I'm using techniques like this to capture the last X or largest X of something that happened within a timeframe.
