Need a Column for Total Logged Time

Need a Column for Total Logged Time

I'd really like to see a column for Views that shows total logged time. Many of our tickets are time and materials. I'm usually not going to bill out 15 minutes until there is more time to bill out, but I sure as heck want to bill out 4 hours. But there is no way I can see this critical information without opening every ticket, I can't even find it in reports. I am attaching an example screenshot of what I am requesting.

Without doing something custom, is this possible now?

It would also be nice to have other formatting options, as shown below, where it is easy to instantly spot items of high priority by color.

Thank You
