Reports Columns

Reports Columns

Greetings,

When I use scheduled reports I select predefined reports that contain predefined number of columns, 
and if I want to select specific columns that suits my needs I have to go with custom reports then choose them to be a scheduled ones, But if I want to create a big number of reports the process will be harder and longer to do, Is there any method to select the columns under the same page of creating the scheduled reports?

Thank you.
