Option for changing random number streams in interactive simulation

When a process is simulated multiple times, the interactive simulation will produce the same output for every run. This is because the same random number streams are used for every run.

At the moment only simulation experiments offer the possibility to use different random number streams for different runs. The feature is called "replications" there.

It would be good to have an option for doing this in the interactive simulation as well in order to see the variety of possible results. Currently the simulation model has to be changed to achieve this which is usually not possible.
