[Therion] Forcing Therion to print centerlines only

[Michael]

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.
