Loot Filter - crystals and materials separation

Hello,
im premium user and one think as grinder and lifeskiller i dont like 2 thinks about loot filter:

1) when setup to not take white items, i cant get any materials for lifeskills (for example Wolf Blood)
2) when im grinding and i want to pick up blue accesores, i get filled by crystals

Would it be possible to create new categories for Crystals and Crafting material that will be sorted by rarity ??

Exampe for crystals: you can choose: white (pick all), green (pick green and better), blue, yellow, none
Example for materials: white (pick all), green (pick green and better), blue, yellow, none
