Is there any way to see "failed burns"?

I am almost able to achieve this in a semi-roundabout way using the userscript Wanikani Item Inspector. One can create a table (based on the included Failed Last Review table) using the Failed Last Review and SRS Level filters, but these have flaws that will not get you all of the items you want.

Failed Last Review requires you to set how many hours in the past to look for failed reviews. One cannot set this to 0 to indicate no cap on how far back to search.

SRS Level could be set to Guru 2 (this is because when you get an Enlightened item wrong one or two times, it drops 2 srs levels to Guru 2). But if you get it wrong 3 or more times, it will drop further, so this filter is not sufficient for showing you all of the items that were Enlightened but failed if you happen to have gotten it incorrect enough times for it to fall below Guru 2.

Perhaps someone else can figure something better out.
