Creating a Summary email of events in SharePoint designer 2010

I have been given the task to create a workflow in SharePoint Designer 2010 to take events that staff book onto and create a weekly email to show a summary of events that are added within a week.

I have so far created a daily email but im finding it hard to create a weekly summary email so it would go something like this:

Event 1
Event Tile: Computer Training
Date: 25/03/15
Location: Office

Event 2
Event Title: Manager Training
Date: 26/03/15
Location: Hall

is there any way of doing this by taking the list items and putting them in Designer to show a weekly summary of events by email? these are obviously the same list columns.

The daily email goes like:

If Current item: title is not empty
Email: email user/users

Thanks for your help
