Hey Gareth,
Thanks for reaching out. Do you know if support filed a ticket? This looks like a bug to me, and I think we’ll need to make a UI improvement to get around this limitation.
There will be a workaround shortly as we’ll be releasing support for creating Data Lake Pipelines via the Public API, it should be available within the next few weeks.
Best,
Ben
P.S. I’m the PM for Atlas Data Lake and would be interested in getting any feedback (aside from this blocker) as well as learning more about your use case. My calendly link is here: Calendly - Benjamin Flast
