WorldMachine do not have option, to prevent File Input node or other similar devices from loading un-nessesary data. It makes your project ultra slow in calculation. It will be good to have something like true-false parameter, that you can control through macro user intarface, so you can disable 999 of your File Input Nodes and use just 1 that you need from those 999 to speed-up your work process and reduce RAM/CPU resources on loading of them
