Visio Adding SubPackage to Package

[randy1200]

I'm using Visio for Enterprise Architects SP-2 (10.0.5110)

I'm creating a UML Static Structure diagram.

I left-click and hold the Package icon, and drag it onto the drawing page.
The Package looks like file folder with a tab at the top. This works great.

I'd like to drag a second and third Package icon into the first, to
represent SubPackages. It's not clear to me how to do this.

I'd also like have the package label appear in the tab part, rather than the
center of the folder part.

Any pointers on how to show subpackages and label in the tab woulod be
really appreciated.

Thanks,
Randy
