Option to fix date setting when generating balance/p&l reports

Maybe an idea for a next update:

When generating a trial balance/balance sheet drilldown/p&l drilldown, always a correct reporting period have to be entered. I think the most user will use a year or month period:

- 1 january 2012 - 31 december 2012
- or by example  1 december 2012 - 31 december 2012

If i generate a p&l drilldown it always start with the date of today minus 1 month. So generating today will result in the default setting for these reports of 3 december 2012 - 2 januari 2013.

Is it possible to add an option in the companies settings for:
- default reporting period by year
- or default reporting period by month (use current month or last month).
