Yes, you can create a custom field using the **Lookup** data type. By doing so, the users available in the organization will be listed in the custom field. To create a custom field: * Click the **Settings** icon at the top right corner. * Go to _Purchases_ and choose **Bills**. * Select the **Field Customization** tab. * Click **\+ New Custom Field** at the top right corner of the page. * Enter the details and choose the data type as **Lookup**. * Select the module as **Users**, enter the related list name, and save the custom field. **Insight:** A [lookup](https://www.zoho.com/books/help/settings/customization/lookup.html) field allows users to link data from one module with another. * * *
