Describe the feature or enhancement

As we can see, Umami version 2.19.0 has Export function, which is really good step. But I think it can be much better if it export the data by date/week/month/year. We need this because the data we see in the dashboard should be consistent with data we are exported and convenience if we need do something else like combine, merge or convert... etc.

If you also need this, please +1 to help dev team can see and add it sasap, thanks!
