Google Analytics - Email Scheduling last 28 days
===

I've set up some new dashboards and set up an email scheduler within google analytics to go out on the 28th of every month. Currently when the reports gets emailed the results show the 27th of current month to the 27th of the previous month i.e. last months reports showed 27th May to 27th June. 

Does anyone know if there is a way of setting it up so it sends out on the 28th but shows data from the last 28 days? i.e. for last month it would be 31st May to 27th June

Thanks
