Achievements to get those difficult to obtain items

Running low on those lalafall sacrifices to the RNG gods?
Well can we please get some kind of achievements for some of those difficult obtain items. We put our time into this game and for some of us just that unlucky, we just dont get anything in return for all that hard work. Atmas, yes the dreaded atmas, why cant we have some sort achievement atma award for each of them, something like "Do ??? amount of fates with zenith equipped" to get that Atma. Some people put 100s of hours and never see a single atma piece. Those that have atma or animus prolly have multiple classes, will they be so lucky 2nd or 3rd time? And not just Atmas, Leviathan Mirror, Sands/Oils and Im guessing Ramuh will have some RNG. It can be a large amount of times needed to beat to get the achievement and award and I doesnt need to be repeatable, Im sure many would be pleased to at least get it once, for all the effort and not just all "chance."
