You can def do a 2 tier web scraping.
Gumloop has the concept of a subflow.
So your 1st tier is to get the full list
Your second tier is the subflow and will to each one and pull out the info and slack it or something.
See an example I threw together https://www.gumloop.com/pipeline?workbook_id=swqAZAgZt1M93vcggHEhuK
