Hello,

It would be great if the customer update api call could include the same information as the new customer call (at least charges and items).
The issue is that if we want to add many custom charges and items, we need to do 2 * X calls being X the number of items/charges, having a chance of failure for each of them resulting in a partially updated subscription. A failure would be very rare the consecuences are not bad at all, the subscription update will just not include all changes, and missing changes will need to be added later. This can also be helped with some retry logic as well. But, it seems like the update customer api call should be able to do this just like the create customer one.
