asterisk users - Apr 2011 - update CDR fields after Queue

Dears;
I have been faced with a problem that I am not sure about how can I solve
it...
I my scenario there is a variable which will be ready just after the callee
had hanged up and the caller, which coming throw a Queue.

But the CDR fields are logged into DB just after the Queue application. so
the '*userfield'  *field will remained Blank.
is there any way to suspend CDR write INTO DB untill the end of the whole
dialplan priorities?

*exten => research,n,read(dtmf,,1,,,10)*
*exten => research,n,Set(CDR(userfield)=${**dtmf}**)*
*exten => research,n,Hangup*
