I want to have more flexibility with the date filter on Odoo Dashboard. It only gives the option to filter by Year, Quarter, Month, or Relative Period.

This means that we do not have the ability to look at a specific week, or look at our financial year (April 1 to March 31) within the dashboard.

Surely other businesses have this need?

Can someone answer one or all of these questions:

1- How do I add the ability to filter by week in dashboard?

2 - How do I add the ability to filter by a specific time period in dashboard? 

3 - Can you change the "Year" in Odoo to be a financial year instead of a calendar year, resulting in all "Year" filters working to a financial year? If so how?
