Needs non-repeat option – Pretty Random - RNG Review

Would be great for Random Sample Selection for experiment control/treatment groups if it had a non-repeat option. Works ok-ish as is, but is still a bit of work to cross reference which numbers have already been used. Cross referencing for repeats is not the end of the world for smaller numbers, but a lot of effort when your working with thousands of test subjects. Still, great in theory, but would really love to set subject number parameters, push a button, and get non-repeating numbers just like that. Could be a dream come true!!
