I am using Odoo 12 Community Edition.

When creating a purchase order I would like to search for products by a specific vendor in a simpler and quicker way than creating a custom filter. One way that seems like it should be easy to implement is adding a field to the Search More... popout tool that comes up when adding a product to the purchase order.

In this Search More... popup, how do I add to the drop down autosuggest an option Search Vendor for:? 

Cheers,

Sebastian
