KPI Filtered

Hello all,

I have a report that analyses the number of costumers that come to my business, I made some KPI's that compares the number of costumers from a chosen day with the same day from the previous week. 

What I would like to do is that when I open the report I could see today's values compared with last week without haven to select the date of today in the timeline first.

Here is what I see when I open my report:

And this is how I need to filter the data to see today's analysis:

Is there any idea of how can I do it?

Thanks!
