Currently, when creating a purchase order in Mews POS, I can select a supplier, but all purchasable products remain available for selection regardless of the chosen supplier.

This creates inefficiencies and increases the risk of ordering incorrect items. Ideally, it should be possible to associate products with specific suppliers and automatically filter the product list based on the selected supplier during order creation.

Suggested improvement:

Allow products to be linked to one or multiple suppliers.
When creating a purchase order, display only the products associated with the selected supplier.
Optionally, provide a way to override or expand the list if needed.

Benefits:

Reduces ordering errors
Speeds up the purchasing process
Improves data consistency and supplier management
Makes the system more intuitive for operational teams

This feature would significantly improve usability and align the purchasing workflow with real-world supplier relationships.
