Randomized Repeat Times for Scenario Editor

[Aerial]

I love the options we've been given to add events via the scenario editor, but there's no ability to randomize the numbers associated with those events.

For example, right now I can choose repeating raids every X days, which unfortunately means I know when to expect them.  I'd like to be able to specify repeating raids every Y days, where Y is a randomly chosen number between X and Z.

Or I'd like to be able to specify starting equipment randomly selected within a range, i.e. 1-3 randomly selected ranged weapons or a random quantity of steel between 200 and 800, etc. so that the "same" starting scenario still has some variation.

Part of the reason I want this kind of variability is because I can't decouple the frequency and severity of events in the Randy Random storyteller from the built in mood penalty at higher difficulties.  Being able to separate those would also accomplish the goal, I believe.
