Signals Inventory: Is there a way to create a container that will hold more containers?

As a user I'd like to create a container type that could hold other containers inside, for example a box container inside a freezer location, but I am not able to.

Solution: In Signals Notebook 'Containers' can only hold 'Materials'. You can’t create a 'Container' to hold other containers. You can create 'Location' (SubLocation) inside another 'Location' and then place containers inside it: Location (e.g. Freezer) > SubLocation (e.g. Box) > Container.

Steps:
1. Log into Signals Notebook as an administrator
2. Navigate to 'System Configuration' > 'Inventory'
3. Expand 'Locations' > 'Types'
4. Click 'Location Type'
5. In the 'Create Location Type' page:
    a. Fill up the needed information (Names can’t be duplicated)
    b. If you want a 'Grid' box in the 'Add property…' field, select 'Grid Layout'
    c. Click 'Create Type'
