Airport Ground Traffic

I have a couple of questions with regards to ground traffic at the airport, (a couple of things I'm trying to figure out):

 

1. There appears to be a bunch of 'default local' traffic' - for me - Qantas, Virgin Blue, Jetstar, Rex, which is great, (but which I did not select). Virgin Blue (red livery) has been Virgin Australia (white livery) for some time now and I'd like to change the default Virgin Blue ground traffic in UT2 to Virgin Australia livery. Does anyone know how to do that ?

 

2. A heap (over 50 FSX sims) got loaded into UT2 from my FSX directory when I was setting UT2 up and although I can see that they're available for use in UT2, I can't seem to add them to my existing 'default' ground traffic, or, for that matter, remove some of the 'default' ground traffic, or do a 'mix and match' of my FSX aircraft and the default UT2 traffic. Again, anyone know how I can do that ?

 

Thanks in advance for your replies.
