GraphQL orderCreate mutation and discounts

to provide some context, I am trying to migrate orders to Shopify using the createOrder graphQL mutation, the process is complicated and needs some custom development, I was able to do 90% of the job, the thing that blocks me is discounts, lets assume that in the order I am trying to migrate, there exists some automatic discounts, but in the orderCreate mutation there exists only the functionality to attach the discount code, is there any case that I can attach an automatic discount of some kind?
And for my second question, when retrieving orders from Shopify, how can I retrieve the discount title/name of an automatic discount that was applied to the order? I was able to obtain only the value of the discount, not the name
Thanks in advance!
