update signer

Hi, In the JSON retrieved for a Package is there a way to figure out Who (Role/Email) has delegated to Who (Role/Email). After delegation we get the ROLE_REASSIGN event. { "@class": "com.silanis.esl.packages.event.ESLRoleReassignEvent", "sessionUser": "4f124151-9ab9-4956-bf8b-c67454f2b63d", "packageId": "u4aKSxuKuDbI3JtPm1mAjsvYSIc=", "newRoleId": "2bb31fae-fe60-4200-a469-3e71e0c9f81e", "message": null, "name": "ROLE_REASSIGN", "documentId": null } I know we get the link the old Role to the new Role.
