No Manipulate Setting/Fix Setting when using SPP or Montecarlo

It would be a good idea to allow the users to fix some variables when using SPP or Montecarlo. Let's we got Stochastics and even when we can randomize K period and Levels, when it's time to pass through SPP or Montecarlo, even when we select 'Periods' and 'Constant' on SPP (Like the attached picture below), it will randomize pretty much every period, including K, D and S. This would be useful on many indicators that uses many variables, like Bollinger Bands, DSS Bressert, STC, etc.
