Copy previous timecard days order

Hello,
how exactly works the Copy previous timecard functionality?
It seems that it simply copy by day numbers (date), but doesn't take in considerations beginning of month and where is weekend. So when user copy month over month where days belongs to different numbers, then the copy is incorrect. We are using Monthly time card period.

Is there any way how to influence the behavior of this functionality to work better with monthly periods to check where is weekend and copy correctly work days? Or any workaround for it?

On the Responsive UI was possible to select multiple days in the calendar and fill same thing for multiple days with one click, but in Redwood this is not possible and the Copy functionality is also not very useful.
