Date Filter Monday to Sunday Week

I have seen many requests about the date filter for current week using Sunday - Saturday and many users needing the week to be Monday - Saturday. This one issue is messing up my entire project. I understand Knack provides an option for Calendar views but that is not what I am looking for. I have pivot tables and grids that I need filtered by work week which is Monday - Saturday. Does anyone have a workaround or solution for this? This is needed asap and I cannot figure out what to do.
