Virtual Object

HI

I have a tab that QTP does not recognize. So I declare it as a Virtual Object. However I am not able to push it into the 'OBJECT REPOSITORY'. I know this is posible but I am not able to recollect how I did it last time. Can someone help me please? I will be really greatful

Please see the picture attached: I am attaching the picture of the Object Repository with a virtual object present.

Thanks
