Feature Request: Show a latest-hit column when displaying 404s grouped by url

[YesThatAllen]

Summary

I'm viewing a number of 404s on our site, looking to determine which are most relevant.

The default sort is by count, and can't seem to be changed. This is fine, but I feel it's missing a key piece of info.

When was the date of the last hit on any given 404?

Steps to reproduce

Visit redirection's page.
click 404s
click Group by URL.
View the list, which is sorted by hit count (awesome)
Wonder "when was the last time this URL was hit?"

Environment

Latest chrome for mac, using Wordpress 5.0.3, and Redirection 3.7.2. Hosted on ubuntu 16 under nginx and php7.0.
