Are you asking for that field to be the default value of 2, when creating new AZ listings, from SB?
SB has some serious issues, trying to create brand new AZ listings….so I doubt that is what you’re after.
And, I know that in Seller Central, there’s not a way to set your default latency to 2….when creating new listings.
If you create a new listing, from Amazon, by copying an existing listing, make sure the “copy from” listing has it set to 2, and you’re ok.
Or, simply go to the Running grid on SB, and do a batch edit.
I do that all the time on Amazon listings, to change my latency.
If I’m headed out of town for a couple of days, I’ll do a batch edit, and change latency to 5. Then when I’m back, I’ll have SB change them all to 2.
Works like a charm.
