Use DFF in HCM Group evaluation Criteria

Summary

Requirement to use a person or assignment level DFF to determine a specific OTL Layout

Content

Hi We have a requirement that in a later phase of the project we might need to use a DFF value from either the Person or Assignment to determine what OTL Template a certain population uses. 

I was looking at the evaluation criteria on the Create Group task and did not see any options of choosing a DFF Value.

Is this possible ? Ie to use a DFF to determine if an employee will be part of an HCM Group ?

Thank you
