I'm looking to integrate a feature in my quotes that allows me to create composite products. For example, I want to call a main product like "Terrace," select its components (e.g., 10 bags of concrete, 3 wooden slats, 20 hours of labor), and have the total price automatically calculated and displayed on the quote line.

However, I can't achieve this with current combos or packs, as I can't select specific quantities for each sub-product. The quote calculator also doesn't work because it doesn't link to my stock and sales. As an Odoo integrator, three clients have requested this feature.
