Report default date

I run a lot of reports.  I would like to set the RUN Date of ALL reports at THIS YEAR.

Currently it's at past 90 days.  SO each time I change a report, I have to go change the date and this has caused a couple errors from my assistant thinking she was running THIS YEAR and only ran past 90 days....

I want the DEFAULT as THIS YEAR on ALL reports, I don't want to have to set EACH one as custom...as that's insane...wayyyyy too many reports.... 

just a default.... ???
