Create custom date range with same start date and different end date

[anam0904]

How do I create a custom date range that has the same start date but different end date? I want the start date to always be on Sunday, but the end date to be the current date. Ex: On Wednesday, I want to send myself a look with a date range from the previous Sun-Wed, and on Thursday (from Sun-Thurs) and Friday (from Sun-Friday), and so on. Essentially, it’s a cumulative look. Is this possible to do?
