Is it possible to change start of week day?

I (like a lot of people) have a club ride on Sunday which I have no control of the XSS. If Sunday was the first day instead of the last it would be easy to plan the rest of the week. Is it an option or would it need to be a future request?

XATA moves away from Mon-Sun or Sun-Sat week definitions and instead opts for a rolling week. Using arbitrary end of week definitions doesn’t provide the flexibility to adjust. Sometimes you have a club ride on Sunday and the three weeks later you have one on Monday or Saturday. If you wish to plan for the week, Just use XATA and schedule your activities. Use the Pacer to map out no deficit by the end of the week.
