Just gonna bump/update this, there should be a one-time-purchase permanent "item" that lets you filter drops (i.e rolling item crate 1's and don't want standards? Filter them out entirely, so they won't go into your inventory.), but then a separate item for turning things into keys. Perhaps depending on the tier, costs would differ. Totally spitballing here, but something like:
(All of these would be stackable items that, when not locked, would automatically turn 10 of an item into a key. They would NOT turn anything with a suffix or traits (perhaps an F1 menu setting to play around with this) into keys.)
100 Coins/1 Fragments: 3x Tier 1 Keyers
250 Coins/2 Fragments: 3x Tier 2 Keyers
500 Coins/3 Fragments: 3x Tier 3 Keyers
1000 Coins/5 Fragments: 3x Tier 4 Keyers
1500 Coins/6 Fragments: 3x Tier 5 Keyers
Again, just totally random numbers, but they'd stack infinitely and take up a sole inventory space. If you have one locked (a stack/individual), it won't "use" them to make keys automatically.
