Ability for Manager to Manually Select Approver(s) for Performance Documents

Summary:

Hi all- we are in need of seeing if there's an ability for line managers, when carrying out the performance evaluation process, to be able to manually add and select an approver/participant in the approvals workflow chain for approving a performance document. (This would be the 1st chain of approvers, which would be followed by a second of which we would base upon managerial hierarchy) Currently, this was achievable in ePerformance. A workaround we saw was possibly allowing the routing to go to the manager themself first, to which they would then "reassign" the task to an individual they choose,
