Here we go again :) There should be NO reason to have to have some sort of probe function, with it's additional hardware and code to touch off a tool. You should be able to move the tool manually during a tool change operation and zero it. Every CNC controller I've ever seen has that facility, except LinucCNC. Feed hold and jog is another. I've discussed this with more than a dozen CNC companies who I have dealings with regularly and not one would entertain any controller that could not jog during a feed hold or tool change.
