Time tracking report - Tasks with time entries in multiple days

I would like to see in a dashboard the time spent in all my tasks in a day, week, month… But the way the dashboard is setup today doesn´t allow me to do so, because it does not use the date of the time log in the timetracking column. Instead it uses the date of a column date, so it adds all the time spent in a task (in my case, a subitem) and allocates to a single day. For example, if I have spent 10 hours in a task throughout a month and this week I have spent only one hour on it, in my report for the time spent in this week, the entire time spent (10 hour) will be allocated this week.
