I just sent GSO a feature / integration request to their customer support email. I suggest anyone looking for this integration do the same! :D
Here is their support email: customerservice@gso.com

We just signed up today for a trial of ship station, but unfortunately will likely not implement since there is no support for GSO. Please, try to do this -- I think it's a hidden gem on the west coast.
Yes! Please build this integration! We spoke to technical support at GSO and they indicated they would like to make this happen so seems like we just need similar commitment on ShipStation side. Please re-consider this, as it would be huge for West Coast clients. (fingers crossed!!)
We need this to complete our shipping automation and not being able to use GSO is a hassle. Our company does large Banners mainly in the Western US and GSO is the main carrier for overnight delivery.
