Search for unique records pipeline

Thanks for the help Mark and Mike. I thought this would be a pretty niche thing. I ended creating two checkboxes, one for whether it has already been imported (gets checked during the pipeline) and another for the lowest record ID that hasn't been imported (formula field). The pipeline is first triggered manually with a button that changes a date/time field and at the end calls another pipeline that searches for the lowest record ID to be imported checkbox to be checked and changes the date/time field to trigger the main pipeline again.

That way it works iteratively through the records I imported. I probably made it more complicated than it needed to be, but it works.

Thanks again,
