Yes. If you want to set multiple fixture offsets, say G54, G55, G56, and G57, and don't want to constantly regen the tool path for each one. Or just setting the G54 X, Y and Z offset one at a time. Do you want the tool path to regenerate three times? Or just once by pressing a button after you set all of the offsets?
The screen is flexible enough so that you can make it do whatever you want. There is nothing set in stone. However, it is setup for normal workflow by default.
