# Linking product specifications

> A product specification based on the **Data-Driven Editor** workflow allows you to add the Data-Driven Editor (DDE) to your personalization process.

To set up the editor, navigate to the **Product Specification** section in your BackOffice account and click **Create**.

## Selecting a workflow

When the **New product specification** page opens, on the **General** tab, define a product name, add the product description, and select the **Data-driven Editor** personalization workflow. You can find it under the **Standard** folder.

When you need to change the default settings of these workflows, copy the file to the **Custom** folder and make your changes.

## Selecting a design

On the **Attributes** tab, click the **Design** field, then a folder tree with designs [connected to a data scheme](https://customerscanvas.com/docs/hub/admin-guide/data-tools/concepts/data-schemas.md#connecting-data-schemas-to-designs) will appear. This connection implements validation of the input fields.

However, you can go further and enable prefilling fields in this design with an optional attribute **Data set** as described below.

## Enabling the prefill option

To enable prefilling the design fields in the editor, you must specify a DST file in the **Data set** attribute. This file may contain, for example, a database of employees, and when the DDE opens, you can paste the records into the editor one by one to verify their appearance.

This option adds the **Prefill** buttons to the editor for pasting data into design fields or clearing them.
