Reports - based on Last Week?

Hi Team,

I need to run a number of reports every Tuesday for activity the previous week.  When defining the filters, there is no Last Week option.  How can I run the report based on the previous week (Sun - Sat or Mon - Sun)? 

I don't want to use Last 7 Days, because then I miss out on last Monday and incorrectly include yesterday.  

I also don't want to use Last # Days (where # = 8), because this would incorrectly include yesterday.

I really appreciate any assistance you can give on this.
