To update an existing compartment, you can the right-click on the compartment you want to update. In the appeared context menu, select edit

In case you update a sample container (i.e a box), you can change the compartment name and the numbering of positions in the compartment. When updating a segment (i.e a drawer or tower) you can change the compartment name and you can limit the number of compartment that can be added in the updated compartment.

Click Save Changes update the changes. Note that you cannot update information of existing compartments by updating a storage unit. Making changes here will only affect the configuration of newly added compartments.
