Report builder can crate a segment from an excel column. It is slow and requires you to create a data call first. I propose that this function we moved to the WS Segment tool. nd that it stay as a list so that it can easily be updated. We work with a very large website that requires complex segmenting based on shifting business rules (therefore web page metadata will not work). We receive the lists of URLs from the content owners across the enterprise. Creating and editign segments is a lot of work to achieve the end goal.
