Configure IE mode for Microsoft Edge

Question

I've collected site discovery XML files for IE mode for Edge, and compiled them into a site discovery XML file. Once I've opened it in the MS online tool for configuring IE mode for Edge, there are over 88,000 URLs. After selecting "Remove non-issue sites", I'm down to 47k sites.

When I click on "Not configured" it says to open the site in Edge and then in IE mode and compare the results. It seems that this wants me to address each URL one at a time, despite the fact that you can obviously bulk configure them. I've been searching Google, but I haven't really found a good rule of thumb for bulk configuring. For example, if I filter down to compatibly detection "ActiveX Control", would it be best to select all sites and bulk "Set to IE Mode"? Or for "X-UA Compatibility"?

I haven't been able to find a chart or any type of best practice for bulk setting the various sites.
