New Spell Tag

For many spells the material components are merely fluff, largely ignored since they can be replaced by use of a component pouch, arcane focus, or holy symbol. I would like to see a tag added for "Expensive" spell components that cannot be replaced in such a way. This would be greatly helpful to track spells such as Arcane Lock, Augury, Ceremony, and Chromatic Orb, among others, that frequently slip through the radar.

Expensive components are expected for some unique or high level spells, such as Awaken, Astral Projection, or Clone, but many of the lower level spells that are meant to be balanced and restricted by their components go unnoticed.

By adding this as a tag on the spells with valued components that cannot be replaced, it would make them easily searchable in the current system, and would be a relatively simple fix. (*Currently there are 15 pages of spells that sort out by having material components, but only 2-3 on any given page from that list are expensive.)
