QBench has several locations where you can configure items like status which aren't located in the Fields and Data Types page. This icon is located in areas like the Inventory, Assays, and Batches sections.
By clicking the gear, you will open a new page where you can create categories for these sections.
Clicking on +New Category will open a new window that allows you to input any title that you wish.
Upon creating a new item, it will be available under a dropdown menu with the same title as the section. You can also make a previous item inactive (unable to be used) by ticking the checkbox next to Active.
