Need to increase Command Timeout from default of 100 seconds

I have a large network with about 1500 IPs assigned to it that is timing out when trying to retrieve it. I need to increase the timeout, How can I do that?

This is running against VCD 5.1

PowerCLI C:\Program Files (x86)\VMware\Infrastructure\vSphere PowerCLI> Get-ExternalNetwork -Name "INET-1-A" | Get-CIView

Get-CIView : 6/21/2013 1:20:56 AM    Get-CIView        The operation has timed out

At line:1 char:57

+ Get-ExternalNetwork -Name "VMPUB2-INET-1-A" | Get-CIView <<<<

    + CategoryInfo          : NotSpecified: (:) [Get-CIView], CIException

    + FullyQualifiedErrorId : CloudImpl_ViewServiceImpl_GetGetCloudView_Error,VMware.VimAutomation.Cloud.Commands.Cmdlets.GetCiView

P.S. If anyone knows of a way to improve the performance of the request in vcd that would be nice as well, seems like taking over 100 seconds to return the network is pretty bad.
