  hi @Papad you'll do this in Generate Attributes. I do this all the time. Something like this:

  @sgenzer Thanks for your answer.
  What I really want to do in not only to show in each row which week we talk about.
  I want my dataset to be merged. For example, Jan 1 - Jan 7 are seven rows but I want it in one as Week1 and all the attributes added to each other automatically. Is there any way to do this?
  Thanks again.
