Hello!

First of all, thank you for releasing an official DHL plugin for WooCommerce. This has been a standing issue for years in Germany and this plugin makes integration much, much easier.

That being said, I would like to propose a few improvements for the upcoming versions, if you see them fit:

1. add a filter to determine which payment methods require CashOnDelivery; if a shop uses a different payment provider, the CashOnDelivery method may be a different one than the default ‘cod’ (for example, https://www.payone.com/en/payment/cash-on-delivery/).

2. allow the creation of multiple labels per order, and of labels per line item (respectively multiple labels per line item). For example, it’s not always the case than an order gets delivered in only one shipment – off the top of my head, items may not be in stock, which might result in partial deliveries. Another concrete example is a shop I used to work on which offered electronics repairs – the customer would send in their electronics via DHL Retoure Portal and then a label would be generated for sending them back – however, customers would often book more than one electronic device repair and ship the devices at different times, which required the generation of one label per item always. Also, this is helpful when dealing with warranty cases – the same product might therefore require up to 4 labels (in Germany, at least, where the law requires that the customer be allowed to ask for warranty up to 3 times).

Thank you!
