I've searched through mailing list and manual, but couldn't find any solution. Maybe someone has an idea how to achieve that? I'd be grateful for any help.

Since there exists no shrink-wrapped solution, you'll have to develop 
one. Express mathematically what you want to observe, and then consider 
how g_traj and g_analyze might be used to achieve it.
