I need to create a filter on sales admin order grid that only shows the orders that contain products from a specific source.
I found questions that sort of answered this for Magento 1 but not for Magento 2. Most of the solutions add a custom column to the grid and filter on that.
I need this filter to be executed on page load. If the order contains products from source A, the admin should not be able to see orders for products from source B in the grid.
