I've worked this out and seemingly you need to edit the net.conf and the netid.conf
note the netid.conf seems to be indexed with an incrementing number after the last tab space.
eg
netid.conf
Name - Subnet - Colour - Retention - Weight - Index
Company.Site.Zone.Name 10.0.0.0/27 #990000 2419200 85 114
net.conf
Name - Subnet - Colour - Retention - Weight
Company.Site.Zone.Name 10.0.0.0/27 #990000 2419200 85
Hope this helps someone as support said "This isnt possible"
