End Mill Break Recovery Options?

Just had this happen today. Running along just fine, 2 hours into the job and then the End Mill snaps with about 5 minutes to go. What I would like to do it is:
 
1.Pause
2.Stop the spindle
3. Jog to a place where I can change the end mill
4.Touch off again to set my Z
5. Resume the job where it left off (or even better back up a few line of G Code)

Is this possible?
Thanks,
HH

I have done it in the past manually, it's not trivial. Best way is to edit the g-code and reload, trim away everything after the preamble to the last plunge move.

It's not possible to just resume the file from the point it ended as that is most probably right in the workpiece without a safe direct line from the tool height probe position. So we need at least a safe ramp/plunge movement. And the preamble needs to run again, to use the correct tool height offsets, tool diameter compensation, bring the spindle up to speed...

I don't think there can be a generic resume-at-position for this that fits all. Some tools that have a certain orientation or don't enter the workspiece colinear to the spindle, e.g. t-slot cutters, profile cutters in general, taps. And then there's five axis machines.
