[Therion] station-names for map definitions

Good evening station-names <prefix> <suffix> is a nice little statement that I use all the time for scraps, and occasionally for centrelines. Checking in the Therion Book just now, it seems that that is all station-names works for, which I guess is kind of logical, as those are the only entities that contain stations. I was just looking at my map definitions, which contain lots of; <scrap or map name>@CaveName Statements. And thought that it would be nice to have something like station-names to avoid having to repeat the @CaveName suffix ad nauseam. I tried using station-names in my map definition, but get the admonishment "station-names specification not valid for map" Thoughts? Easy to implement? Bruce
