We will review this issue in due course. Initial thoughts: Any changes to the way in which the “Assigned to” functionality works need to be carefully considered because there may be unforeseen knock-on effects. Additionally not all Workbooks customers use this functionality in the same way e.g. Just because an Organisation is being assigned to a different user, should all opportunities be re-assigned? If multiple sales people sell multiple times to the same organisation there may be multiple ongoing and historical opportunities that need to be assigned to different people.David Turner commented
I think it makes sense that if an Organisation record is assigned to a particular team member, all Person records for that Org should automatically be assigned to that user, by default.
