@aaouviz, you can instanciate controller, so that one controller would change parameters of several nodes. You just need to plug controller into one bitmap node, then SHIFT drag that node alone and it will share controller with its clone. Unfortunatelly, if you already has node tree setup like in your screenshot, then the only way to controll them all, is either plug the same controller into each node, or to rebuild the node tree from scratch.
@hurrycat, Corona color correct node already has that feature built in. Look for option "use settings from map". With it you can set-up Color correct nodes tree, where one master CC node would control several slave CC nodes. So far only Corona CC has this feature, but devs said that eventually it may be implemented into other Corona texmaps.
