Account Invoice Send Template

When you select several invoices in the Accounting app and use the batch send action, Odoo opens a wizard to send and print them. This module adds an extra field to that wizard where you can choose the email template to use for the whole batch.

• The template list only shows templates built for invoices (account.move), so you cannot pick an unrelated template by mistake.
• The field is optional: if you leave it blank, the standard Odoo behaviour applies and the default template is used.
• The chosen template is applied to every invoice in the batch when you confirm the send, so all customers receive the same layout and wording.
• The selection is stored on the invoices being sent, so the sending process picks it up instead of the default one.

It touches the invoice model (account.move) and the batch send wizard (account.move.send.batch.wizard), and only adds one field to the existing wizard screen. No new menus, reports or scheduled actions are created.
