Archaic Ancient Relic- Basic Oreha Fusion Material @Farm

Over the last few weeks I have noticed that I am no longer able to really get many Archaic Ancient Relics(the common material) from my farm and am instead getting tons of Faint Ancient Relic & Ancient Oreha Relic. Unfortunately there is no way to trade down resources only up. Aka Its becoming increasingly harder to actually make Basic Oreha Fusion Materials and it feels like you are punished for growing your farm and skills. Is it possible to add in a trade down feature at the vendor? or simply give a better ratio? Being able to make your own Basic Oreha Fusion Materials is a massive fix to a super annoying pain point when honing!
