Perfect, thank you!!

Is it possible to split a large sector? I've created a map with two distinct areas which are somehow the same sector; despite a door separating the two areas, sounds in one area activate monsters in the other area, which is not what I expect. Is it possible to split these two sectors up without just deleting all the geometry and recreating it? The 'Disconnect' operation for sectors just splits the entire sector off from an unrelated sector to the right of them. See the attached Eureka screenshot...
