In my opinion it would be very useful if you could make the same adjustments in one stretch for a selected set of scenario's. Similar to an adjustement you make in the base scenario that effects all the underlaying scenario's but than for a specific selection of scenario's. It would be handy to restore an error that occurs in several scenario's (scenario' that are all a copy from the same scenario)
I would like an option (possibly on commit?) that pushes changes made in one scenario to - all objects that are still linked i - all 'child' scenarios: ie "Copy an existing scenario" was used on creation.
