Edit plugin ''WooCommerce Dropshipping ''

I need to edit the plugin ''WooCommerce Dropshipping'' - Developed by OPMC. This plugin automatically notifying suppliers when their products are purchased through your store. Everything works fine. But I need only 1 or 2 supplir orders to be processed. When a client tries to buy an order of 3 or more suppliers, that order is not processed, the client cannot reach the checkout and an error message is shown in the shopping cart. For example, something similar to when you try to buy a product that is no longer in stock. I only want to accept orders of 1 or 2 supplir, because when an order has more than that it is very complicated. Hope you can try some local woocommerce site or test site you have. You will not be able to access my serve or test something before it is ready, because this may affect my current orders. Please install the plugin. Create 3 suppliers and 3 products. Add a product to each supplier. Simulate a purchase, but when you get to the cart, the error message is displayed when you add the 3 products from different providers. You must edit the plugin so that it blocks the order and displays the error message: Error de pedido: Muchas bodegas de despacho. Por favor contáctanos por WhatsApp.
