Change time period in Insight basis a control

Hi can anyone please help me with changing the weeks or time period on an Insight? Suppose i am calculating a WoW basis Wk and WK-1 , and I want to have a Week control that controls which week’s data is seen in the Insight and not automatically assume the previous time period

It would also be helpful if I could set a date for the insight - as it is a WoW insight and my data updates everyday, it calculates WoW for half a week as compared to the full week of the previous week. Is there any way I can ensure it considers only a full week data?
