Yes, we have a Mori and a Niigata that we turn on those options for milling but have to turn them off when drilling. Because of that we made it selectable in operations machine control. To do that we added the event to the ude.cdl file and also had someone write the post builder custom commands. If you don't use any canned cycles you could simply add the text at the tool changes to turn the option on and off. The latter method is not the most elegant but it's simple if you don't need to turn it on and off in your operations.
