Using GraphQL to edit shipping line amount on a paid or authorized orders.

[quickjeff]

Hi Ya'll, 

Im currently working on a private app that is used to edit orders automatically based on inventory changes. 

I have been able to edit the line item quantities but now I need to edit the Shipping Line Item Price. 

I can query the Shipping Line but dont see a way to edit the price. Any creative ways to achieve this?

Looking for tips, advice and recommendations on this one as I cannot find anything under mutation docs in the dev docs. 

Thanks!
