Hi Steve
Unsure what you mean by 'tour' network flights.
If you mean 'track' them, then yes this does work now - certainly in version 3.12 beta (and I think from 3.11b).
Just click on the 'Pan Map with Active Flight' icon, having selected the network flight you're interested in.
Was problematic in earlier betas as the active flight kept coming unfocused.
I have tracked many network flights without problems since latest betas released.
Hope that helps
Chris
