Convert default Alert Report to dashboard?

While the configuration options available in the Alert List widget can get you quite close to the HTML version of the report, you might also consider embedding a report in your dashboard if you’d like to achieve an exact match, we cover a method to do so here: https://www.logicmonitor.com/blog/viewing-logicmonitor-reports-within-dashboards

I sort of figured it out, but its ugly and clunky. 
Copied the built in Alert List dashboard and made a few small tweaks. Its a bit annoying you can’t seem to choose these columns on a fresh dashboard/widget, seems artificially limiting. 

Added Severity: Critical

Added Cleared : All

Yeah, you can add all the pre-built or existing stuff. But its not like it would be on a normal Table Widget where you actually get the configure the Row/Column sources. 

I guess I’m slightly stuck. The out of the box Alert List has zero flexibility and when you create a new Table Widget, the Alert information doesn't appear to be something you can select as it's not a resource or a field attributed to a resource as far as I can tell. 

The end goal here is trying to get a dashboard to see how long things were down. I’m starting to see its likely just gonna be a 100% from the ground up built with using custom sources. 

I have a datasource in my Sandbox called “Report to Text Widget” that will take an existing csv report, convert to HTML and then display it in a text widget.  I’ve used it before but it has been a long time and frankly I can’t remember how to set it up.  Mike Suding had instructions on his blog on how to set it up but I’m not able to get to his site for some reason. 

Anyway, it might be something you could use.
