Creating shape-templates in Microsoft Visio

[Joergen Vig]

Hi,
I use Visio in datamodeling and want to make some default
entity-shapes that contain some default columns.
Designing and adding the shape to a stencil works fine.
But when I drag and drop the custom entity-shape to a new drawing, it
looses all columns.
Is it possible to keep default columns in a entity-shape in Visio 2003
(10.0) and use it as a table-entity template ?

Thanks
Jorgen
