Hi,
I also like "unmanaged approach". It would be also fine if user could change that behaviour later. But regarding autogenerated scenarios I also see another huge problem....
When scenarios are autogenerated, they are generated in weird way, cause copies are made for each room - that means that you get separate copies of same scenario for each room. And then editing them is a night mare (I think that Wizard for Scenarios also does that).
It would be muuuuuuuch more convenient if we fix such behavour also. I don't use Scenario Wizard because of such silly behavour. I only use Advanced-Scenarios, where I can create scenario and then just click rooms it will appear in and this works much better, since I have only 1 scenario that is easy edited...
