At the moment, our tool doesn't support bulk uploading of automation rules, and we understand the manual process can be quite time-intensive.
However, here's the silver lining: we're excited to share that the functionality you're looking for – the ability to duplicate automation rules across various marketplaces – is already in the works. You can expect this feature to be fully rolled out by the end of October at the latest. Stay tuned for the upcoming enhancements!
