SS2: How to change the Style of 100 alignments in one click?

Hi guys,

I have a problem with changing style for a big number of alignments.

In my Geometry file I have around 100 of horizontals for troughing and 100 for cables lines. Everything with Default style :( I need to display only part of this Geometry horizontals or display everything but in different line's style.
Any idea how can I make some filter for alignments?
Even if I want to change style I can chose only one at a time not 100...
