If you have added
advanced properties while creating a WorkSpace, like custom date or custom text
then you should use below expression:
Note: WorkSet.CustomPropertyName

Using this expression, you can define and redirect the coordinates of the Global Origin in the design file. The default design file Origin displays the default values.
You can define an Item Type property by using one of the GCS Expressions in the Expression filed or using Expression Builder.
