Yes, therion should do this, but it is difficult to say, what is wrong  
with your files. Could you please send me some minimal sample where it  
does not work?

Another point:

When I read this e-mail once more, I must correct my self. Currently,  
there is no way how to do it :( Either you will show all centerline,  
or you will hide all centerline.

Solution can be draw centerline from data (not from scraps) with  
different symbol. If need it, I can do it quite fast. Do you have some  
terms, when your maps need to be finished?
