The way I do it is to create all the layers needed and then, with a text editor, copy all modulators needed and paste it to a new document, search and replace all variables you can at once (layer uid and any other shared by all mods) and paste the result at the end of the panel. Open the panel in Ctrlr and change individual variables in the modulator list window. This way you have the same layer repeated with all mods in their place. It’s still time consuming.
