eB Calculated MAsk

I want to include the following class values in the document calculated mask :

Level and Location are the classes under the Class Group "Locations".

In the Calculated Mask syntax you can include "Location" as "Locations.Location.Code" as this is as available value:

And it would be shown as follows:

However the syntax "Locations.Level.Code" is not available. Is there anyway this value can also be included in the Calculated Mask syntax?

Regards
