[Therion] Forcing Therion to print centerlines only

Hello, Having the need to produce a map showing only centerlines with station names, I forced Therion to produce such by removing all "input *.th2" statements. With growing number of such statements in various files this becomes unmangeable. Is there a way (a switch) to force Therion to print only all centerlines, without any scraps or sketches? I tried "unselect" but that command appears not to work. Michael.
