Hi Jason,
You can pull the approver information from issues using collections in the field. Here's an example of what one of mine looks like.
displayname=Approver
listdelimiter=<br>
listmethod=nested(approverStatuses).lists
textmode=true
type=iterate
valueexpression=CONCAT({approvalStep}," - ", {approvedBy}.{name}, " ")
valueformat=HTML
Hope this helps,
Teale
