Designate specific monitors to be available to Windows guest

Is it possible to configure Parallels so that Windows only see's two of 3 available displays?

- Built in display on Retina MBP
- External Monitor over mini DisplayPort->VGA x 2

I just want Windows to be able to see and make use of the two external monitors.

I want to keep the Macbook screen itself only available to Mac OS, but I want to put Windows into full screen over the two external displays.

Is this possible? If the above doesn't make sense I will try and explain in more detail.

Basically I need a setting to make it so that the guest OS only see's two monitors that I specify (I can change this setting when I am working mobile and don't have the displays).
