It would be great if custom forms in Shopware 6 could be pre-filled using URL parameters – for example, in use cases like invoice corrections. This way, values like order number, invoice number, or customer ID could automatically appear in the form when the link is printed on an invoice.

Example URL:

www.shop.com/invoice-correction?orderid=123&billingid=456&customerid=789

As a result, the order number in the custom form invoice-correction should now be pre-filled with 123, the invoice number with 456, and the customer number with 789.

At the moment, this only works via third-party plugins (e.g., ACRIS CMS Pro). It would be great to have native support for this in Shopware.
