Trending for 4-4-5

[#1]

I would like to be able to see the trending graphs and tables in SiteCatalyst while using our 4-4-5 calendar.  I can see the current, 4 week prior and 52 week prior comparisons when I log into the current month's report but the comparisons disappear if I change the timeframe.  

This is extremely critical to the success of our business.  Is it on the roadmap and when will be completed?
