As I mentioned in the other thread: Originally this mod was just a 0.13 (now 0.14 too) port of an old 0.12 abandoned mod that I uploaded here by popular request. I'll create a github repo in the future. Mod portal doesn't notify me when people post messages here. I have to intentionally come looking for them.
As for your question that is the way the original mod did it. My port is really just fixing the info.json file. I believe, there is a mod event for when settings are pasted. If it works the way I hope I should be able to make a GUI to allow for configuring the multiplier the way you want per recipe and to include/exclude and modules/beacons in the equation at the time of the settings paste.
