Sort by date ROM was added?

[krisjohn]

Any chance the rarity guide can be made to sort by the date a ROM was added to the collection? I've got a collection that was probably complete a year or so ago, but I'm not sure what's been released since then.

 

Alternatively, I have a zipped directory listing the the BBS won't let me attach. Anyone with enough time on their hands to see what I'm missing? PM me/

 

TIA.
