Getting artboard number from imported by reference AI file

I need to know if there's a way to get the Artboard number from an "Imported by Reference" Adobe Illustrator file?

By looking at the Object Properties while the imported by Reference AI graphic is selected, I can see the file location and also the Artboard number, as shown below:

When getting the file location using InsetFile, the artboard number does not show as part of the file location.

Thanks.
