It sounds strange, like a Russian doll, but it really needs this feature.
E.g. I have several similar variables:
variables 1 = 0
variables 2 = 0
variables 3 = 0
variables 4 = 0
....
variables N = 0
They all have similar patterns, maybe the pattern behind is not exactly a number or a certain word combination.
If use the event to modify the variables like make all variables +1 or -1, it seems that there is no way to pass parameters through a Function. I have to Set Value one by one. There are as many variables as I need to operate.
