Stock Picking Package Groups

This module adds a new setting to the Operation Types in Inventory. On the operation type form, next to the existing 'Show Entire Packs' option, you now find a 'Package grouping' field with two choices: 'Standard grouping' and 'No line grouping'.

• Standard grouping (the default): when you use the 'Put in Pack' action on a transfer, all the detailed operations are grouped together into a single package.
• No line grouping: each detailed operation is packed separately, so every line becomes its own package.

The setting is stored on stock.picking.type, so it applies to all transfers that use that operation type (for example, all outgoing deliveries or all internal transfers). The behaviour is applied when the packing action runs on stock.picking; the module changes how the package is created based on the chosen option.

No new menus, reports, emails or scheduled jobs are added. The only visible change is the extra field on the operation type configuration screen, and the different packaging result when you pack a transfer.
