Anyway to filter out HL2 textures for TF2 mapping?

[Street_Wolf]

Basically what the title says. Is there anyway to filter out the textures that are from HL2 when I make a TF2 map? It seems like it would cut down on the time it takes to find the right texture for certain spots if I didn't have to also have a bunch of textures I have no need for getting in the way as well.

Type in Tf2/(Texture)

type in tf2 under keywords, all the tf2 textures have an additional line in their vmt: "%keywords" "tf2"
