Doesn’t look like it unfortunately.
To all those posting 3rd party apps as solutions for this issue also look further back previous ‘solutions’ that are no longer found as they have been abandoned. This function needs to be in the core of the product not a 3rd party app. In addition this being a 3rd party app if the api delays it will seriously impact conversion rate on the shop store at the most critical step of the sale. IT MUST be part of the core product.
Why is this so hard to develop it’s not some major feature - you have a table internally just make an interface to edit it / upload to a csv. I had posted previously an even more ideal option to just have rate of item + weight calc but clearly that’s never going to happen.
Dear shopify - our next renewal is up june 2023 and we normally update for 3 years the 2133 USD option. We are going to have to evaluate whether to update this time or move on. Not liking the absence of response or any sign of interest on this of late.
