OK, I’m blind the ‘Collection report’ has an option for aging columns that meets the need for now.
One issue from a user perspective is that a "Collection Report" is typically just for reporting on people that have been turned over to "collections".
This report is really a Accounts Receivable report.
It also is more than a report since it seems to be able to mark accounts for collection, though it’s unclear what that does or what you are supposed to do with the data dump that is displayed.
Seems like two different jobs, to me. Reports should read-only activities.
Otherwise it should be a "Collection Batch Process" .
There should be a definite difference otherwise it’s very confusing to the users where to do what.
