Month Range Selector

Month Range Selector

I have spent a good amount of time looking through the various date selectors.  What I can't find (and I wonder if I've missed it) is a datepicker with the ability to allow users to select a range of months.  I am dealing with financial data that is month-related but not really date-related.  So my users just want to select jul '09 - feb '10, for example.
 
If there isn't one, may I humbly recommend that one of the date range selectors incorporate this ability.
 
Thanks for all that you do,
