Is there a way to open two months at the same time in iCal?

I have recurring events for every month in 2009 and want to replicate them in 2010. I do not want to just extend the stop date because there will be subtle changes to the 2010 items that I do not want changed in the 2009 versions. I would ideally like to open Jan 2009 and Jan 2010 next to each other and copy the 2009 event to the 2010 calendar (the appointment copy does not copy the recurrence info which is good). Is there a way to show either two instances of iCal running or 2 month windows?
Thanks!
