Request fulfilled Suggestion: Add filter "no/0 sockets"

Unless I'm completely blind, the advanced filters include anything from 1-6 sockets but not 0.

So say I want to get a 3 socket

Archon Plate (arbitrary example), I can search for 3 sockets. Or I can search for any of them to see all Archon Plates. What I cannot do however is to search for 3 sockets and 0 sockets specifically (be that simultaneously or independently) to find all listings that give me either the 3 sockets I'm after or 0 sockets to use in a cube attempt to get 3. To find those 0 socket ones, I seem to have to drop the socket filter entirely and then sift through all resulting listings, including those with 1, 2, 4 and so on sockets.
