Splendorous materials only available in Crystalline Mean

Catching up on the Relic Tools of last expansion, and I've noticed the Splendorous materials(lv90) (Select Cudweed, Select Marble, etc) are only available from the vendor in the Crystalline Mean. While Materials from former Dragonsong(lv80) sets (Oddly specific Skin, Oddly Specific Sap, etc) can be purchased from any scrip exchange.
Makes it really annoying trying to stock up when there's no Collectible Appraisal nearby and a firm 4000 scrip capacity. So we have to jump between one location to offload Collecibles for scrip, then hop back to the Crystalline mean to purchase the "Select" materials needed. While the Dragonsong materials share similar Limitations in usage, they are available anywhere, yet Splendorous materials require this to and fro.
Since this is an expansion old already; Can we get the Splendorous "Select" materials added to the general Scrip exchanges available in all cities?
