BPM workflow for backdated termination in V3 Term

Hi,

We have a requirement to trigger a workflow when termination date - term action date is >2 days. on BPM - AssignmentTerminationsApproval rule, there is no way to pull Creation Date. We are looking for Creation date and not using Current Date because this workflow should only trigger when the termination is submitted, not when a term is edited/corrected.

This is how I am looking but no way to pull creation date -

Duration.days between(Worker's Proposed Work Relationship.result.Termination Date,Worker's Proposed Work Relationship.result.Creation Date) > 2

Please let me know if there is any other way to do this.
