Hi @ceces, You can't get a report with metrics by date in ACS. It provides OOTB functionality to get the report using the date range and again that won't provide metrics split for each of the dates within that given range rather it will be the aggregate report of the date range provided.
If you're looking to get a granular/customized report you may want to explore other options for extracting raw data (broadlog/trackinglog) from ACS and built reports outside of ACS.
Thanks, Sathees
