You can use the Assign Shape to Category feature to assign specific shapes to categories and subcategories. This is primarily used for Elevation and Plan shapes.

This is similar to the Assign Categories to Shapes feature, but this allows you to customize the shape that drops for a specific category or subcategory.

To access this feature, within the Visio interface, click on a page tab, e.g., Elevation View.

1/ In the D-Tools SI window within Visio, click the View dropdown and select By Category.

2/ To get even more granular, click the View dropdown and select Display Subcategory.

This will display the Product Tree by category, subcategory, manufacturer, and model if you expand all nodes.

In this example, I selected the "Blu-ray" subcategory from the "Video Sources" Category.

3/ Right-click on the subcategory and select Shape > Assign.

This will open the Assign Shape to Category form.

4/ Select the shape you want; in this case, I chose the "Disc Player" Shape.

5/ If you wish to customize the shape, leave the Display shape data on assignment option selected and click OK.

This form will allow you to make many customizations to the shape you have chosen for the category or subcategory.

You can also assign specific shapes to individual products. This is particularly useful if you want the faceplate to be silver vs. black for a specific product, for example.

The steps are the same as above, except instead of selecting a category or subcategory in the Product Tree, you would select a specific product.

If you want a "clean slate" to work from, you can choose to unassign all existing specific product assignments.

1/ In the D-Tools SI window within Visio, click the Manage Shapes button and select Manage Assignments > Unassign Products.

This will open the Delete Product Shape Assignments form.

2/ Check the page types for which you want to delete the assignments and click Yes. This will display the following warning.
