add a nic goes to vlance

Hi,

I have just upgraded from 4.x to 5.1 vco, vcd & vsphere and imported my custom deploy vapp workflow into vco. In vco 4.2 the "add a nic" workflow used to default to e1000, in 5.1 it defaults to vlance (and therefore my win2008 servers fail to see the adapter). If I deploy from the catalog in vcd it goes to e1000 by default. Is there somewhere I can specify e1000 in the vco workflow (have also tried the wire a virtual machine with the same result).

Cheers
