I was wondering if anybody knew how to append the disabledRanges property of the dateChooser Component, kinda like this(assuming cal as the instance name):

_dRange = [{rangeStart: new Date(2009,0,0), rangeEnd: new Date(2009,0,20)}];  
cal.disabledRange = dRange; // will disable all up to the 20th_

I want to turn _dRange_ into:  
\*dRange = [{rangeStart: new Date(2009,0,0), rangeEnd: new Date(2009,0,20)},{rangeStart: new Date(2009,0,22), rangeEnd: new Date(2009,0,31)}];  
cal.disabledRange = dRange; // will disable all up to the 20th then all the dates past the 21st effecively disabling all dates but the 21st  
\*  
something like:

\*dRange += [{my new dates…}]; \*

…But that doesn’t work
