I don't know that we could change the starting selection on a per-scenario basis like that. We can certainly look into it though.
As for returning to previously visited areas, enjoying revised scenarios and experiences similar to what was there in the past... we do have some ideas for such things. Hopefully you'll be able to get a taste of them in our next update, ideally coming somewhen in the month of November.
Thanks for your comments and thoughts. Always much appreciated.
