HCM REST API - Obtain Level 4 Department within Org Tree/Structure

Summary:

When using the REST API, is it possible to query the Level 4 Department within the Org Tree/Structure?

For example, so far we have been able to obtain the following values using the API (in green):

1) HR&L

2) Administration

But is it possible to obtain the Level 4 value (HR&L SS) based on either the Level 5 or Level 6 entry?
