Hi
Suzanne,
Thank you for using Cvent Community!
Steven is right. If you want everything in a single report then you should go for multiple Admission Items in the same event.
Create an Admission Item for your Main Conference and other Admission Items for every single day or combination of days.
Example: If your event is a 3 day conefernce and invitees can either register for 1 day, 2 days or full conference then you would want to create the following admission items - Day 1, Day 2, Day 3, Day 1 & Day 2, Day 2 & Day 3, Day 1 & Day 3 and Full Conference.
Further, if you have an agenda then you should create all of them as Optional Items and then Rules for Optional Sessions under the Advanced Settings tab in the Admision Item to show only the sessions available on corresponding days.
Hope this helps!
Let me know if you have additional questions.
