i made a report that show me installation hours for every item and then i made a sub report that show me total hours in every phase but when i try to run main report its show me the sub report like this

and the sub report look like this

so i should run the sub report every time i start d-tools to make the main report include the hole sub report and look like this
i need to run the main report only to show me the hole sub report without need to run sub report first
