You can do this already with dialplan logic:

exten => _123000,1,Verbose(2,000 selected)
exten => _123001,1,Verbose(2,001 selected)
exten => _123[1-9]!,1,Dial(Zap/g1/${EXTEN:3})
exten => _123!,1,Set(PREDIGITS=${EXTEN})
exten => _123!,n,Set(origcontext=${CONTEXT})
exten => _123!,n,WaitExten(getmoredigits)

exten => 123456,1,Verbose(2,Something else)

[getmoredigits]
exten => 456,1,Goto(${origcontext},${PREDIGITS}${EXTEN},1)

I can't look at your patch until it's posted on the bugtracker, with the
appropriate contributor license filed.
