Adding pricing pro week instead of pro day


I just started entering data of our nice house at the beach. I would like to add the prices pro week instead of pro day, because we are only renting our house pro week. For example: April 23 - April 30, total 445 euro's, is that possible? 

When I select the above period and add the price of 445euro, then the Calendar shows for each day the price of 445 euro instead of for the whole week. 

Thanks for your kind support!
