When adding a Tag, if a specific Location is not available, you have the option of adding that new Location directly in the Tag you have opened. Once the Item is saved, the new Location will automatically populate in Location Manager.

In the New Tag Window, clicking on the Blue '+' Add Icon will open up an 'Add Location' Window.

Based on the Sub Levels configured for a Location in Location Manager, when Adding a New Location,  

you may need to add multiple Sub Levels.  When you have added all required Sub Levels, click the 'Save' button to proceed.

With the New Location added, click the 'Save' button to Save the Tag. The Newly Configured Location will automatically be saved to the Location Manager upon 'Save'.
