Batch Report Printing

This module adds a way to group several existing reports into one combined report. On a report definition (the technical screen behind each printable report), a new "Batch Report" tab appears where you can list other reports to include, in the order you want them printed.

• Each line in that list points to another report and has a sequence number, so you control the printing order.
• Only reports that belong to the same Odoo model as the main report can be selected, which keeps the batch consistent.
• When you save the report, Odoo automatically builds a new template that calls each selected report one after the other, and creates the matching print action if the report is not yet attached to a menu.
• If you later change the list of included reports or the model, the generated template is rebuilt automatically.

A separate "Batch Reports" menu entry is also available, showing the list of report-to-report links. Read access is open to all users; only users with system settings rights can create, change or delete these links.

The module works on the report engine itself (ir.actions.report) and its new sub-report link model (ir.actions.report.subreport), and it depends on the Inventory app.
