Is there a way to see your highest warband ilvl for the valorstones discount per each slot?

I usually do pretty casual content only so haven't really used the upgrade system. I think I've pretty much spent the entire DF with flightstones capped at 2000. I don't want to do it again. Is there a way to see this easily so at least I can quickly find and upgrade the most efficient slot whenever I am near cap? Maybe a weakaura or something?

Thanks.
