Anyone use Feedonomics to handle their Amazon account?

As the title states.

My company uses Feedonomics to push data to all of our marketplaces with our main one being Amazon of course.

We are an FBM only seller.

I am trying to figure out how to Update our shipping template through our feedonomics G-Sheet that we use.

I thought that all we had to do was map Merchant Shipping Group and input whatever shipping template we are going to utilize. eg; “Migrated Template” or “PRIME Template”

Is the only way to change the shipping template manually on Amazon itself?
