Access Manager Assignment Location DFFs in BPM Ruleset

Summary:

We have a cohort in the business that would like to update our approval rules for job requisitions to reference the region of the hiring manager.

Region is a DFF of our work locations.

It does not look like the full location data is accessible via the BPM ruleset. Autocomplete rules also appear to have limited access to information.

Does anyone know how else we might be able to achieve this functionality? Could we perhaps use a fast formula to set a value in the Requisition Creation process and use this?
