Hey there @carmel,
Thanks for joining us here in the community! We are so thrilled to have you with us.
I know that source information comes to us directly in the imported order feed from the selling channel so getting the change made there might be the best bet.
With that in mind, I'm not positive about the ability to modify it once it has been imported. I'll reach out on my end to see if this is achievable in ShipStation directly.
I just meant that you may more likely be able to change it there, as thats where the information imports from.
With that in mind, i'm absolutely still looking into the ability to change that SOURCE information once the order has imported into ShipStation 🙂
