ProofHQ - Add reviewer/approvers on top of an existing Workflow that only requires one approver

[#1]

I want to submit a proof via PHQ and select a workflow that is sent to a team where only one decision is required. This goes to my Editorial team, so just one person needs to make a decision. On its own, this works perfectly. I want to add add'l users as reviewer/approvers too. After i select the chosen workflow, i CAN add more users to the proof (i.e A designer) and CAN select reviewer and approver, but once someone from the Editorial team makes a decision, it makes the designer's decision 'not relevant.' I want to get a decision from the Editorial workflow and a decision from other users added to the proof.
