contact_reports for all contacts since a date

Is there a way to get all of the activity for all contacts since a date using the API? For example, say I have 1,000 contacts on a list. I want to send an email and know how many opened, clicked, unsubscribed, bounced, etc.

It looks like I could get all 1,000 people and get their activity one at a time. I would prefer to get the activity for all contacts or "all contacts in a list" instead of calling them one at a time.

Is this possible?

Thanks,

Randy
