While converting a projects time-sheets to Invoice also optionally attach the un-billed hours to the invoice as a report. (Not aggregated)

From an accountant perceptive they only want to see invoice line items grouped by type/task (Which is implemented).

From the CTO, they want to see the details time logging for a project bring billed for.

Currently, need to export and save as PDF before converting to invoice, and then attach manually the generated PDF. Would be awesome if this were done automatically.
