Setting Neural network training dataset

I am aware that we can use the lines of code bellow to set the percentages of the dataset to be used for training, testing and validating, however I am planning to oversmaple my training dataset and save it in array 'A', and then have array 'B' and 'C' to be testing and validating datapoints. is there a way to use array A,B and C as my training, testing and validating datasets because I only want A to be oversampled

net.divideParam.trainRatio=0.7
net.divideParam.testRatio=0.15
net.divideParam.valRation-0.15
