Create a range date for report

I'm new at salesforce and I have seen that in the reports area I can choose different range of dates like: This month, This year, last year, etc  But I wonder if I can have the option for the "this month and next 11 months".  If I don't have is there a way to create this?  I know I can setup "Customize" data range, but this means that I need to change the report manually every time that the month changes and I don't want to do that.
