Duplicate a report with new Month date

Hello everyone,

I have some data in excel about the sales of march, I import this data into Powerbi. (Just 1 sheet of excel called: Sales March)

After that I made a nice Report (Dashboard) with some pivotcharts and tables.

Now I import new data from April into Powerbi ( Just 1 sheet of excel Called:  Sales April)

Question/problem is: i would like to duplicate my Report (Dashboard) and then connect all my pivotcharts and tables with just the new data of April. (Sales April)

(i dont use any relations with powerbi, its just to visualis the Data for manager)

Thanks all for your support and time

(excuses me for my bad English, its my second languages)
