How to change chart title and subtitle after Drill Down and back to same title and subtitle after Drill up?

I have analyzed the following example,
http://jsfiddle.net/axdcLmfx/

But I am not able to find any methods related to this in DrilDown API in highchartsv1.7.0.
A showcase example would be much more helpfull.
Please help.

If there is no support available also please let me know .
