Observing the command kGenerateLinkCaptionCmdBoss

Hi All

I hope you can help, I like to observer the command kGenerateLinkCaptionCmdBoss so that when it added in the text box with the caption I like to get the text box and add some data to it, I also like to know the link item (uidRef) that was used to run the command.

I have a document observer on the kDocBoss. So I get a call for the kNewPageItemCmdBoss, kAddToHierarchyCmdBoss, etc of the command that kGenerateLinkCaptionCmdBoss runs.

I like to know which IID to AttachObserver to see the command kGenerateLinkCaptionCmdBoss has been done?

Or

Is there a way to tell if the new page item was created with kGenerateLinkCaptionCmdBoss?

As if its a live caption is has a AssociatedTextVariable, but the static caption does not look like it has anything to say the story was created from the kGenerateLinkCaptionCmdBoss.

Thanks
