Wandering Trader Always Trades Items from Biomes that are Furthest from Him

This would instantly make the wandering trader always useful: have him be programmed to always sell you stuff from the biomes that are currently the actual furthest away from where he spawned in. That way not only would he never have stuff from where he is (useless), and not only would he definitely 100% be saving you time and effort, he would serve as a messenger of sorts, telling you "hey bro, by the way, based on these items I'm selling, these biomes are the ones that are far away from you." There can be tweaks to tiers, probabilities, and all that so that it's not so predictable possibly, or not if this isn't too overpowered. Yeah!
