[Psientist]

I had suggested earlier, a "random number generator" kludge. Set up a number of events with the same flag (so only one gets chosen). Set the same variables in each event, but with different numbers. For example

EVENT 1: VAR1=1, VAR2=1, VAR3=1
EVENT 2: VAR1=2, VAR2=2, VAR3=9, etc.

Randomly, only one of those events will be chosen, which can then establish "random" preset values for all your global variables.

Inconvenient, but possible.

Sorry for not using actual mod-compliant language.
