schedule an analysis on last day of month

Content

I want to create an agent that will schedule an analysis on the last day of the month.  There used to be a field in BO called: Last Day of Month but in OBI I only see the dates 1-31.  When I pick 31, I get an error since not all  months have 31 days.  If I pick 30, the months with 31 days will not run.  I'm trying to avoid running it early on the 1st of next month since the filter in the analysis is >= first day of the month.  Suggestions?  Thanks.
