Inspired by the most recent post on the LM blog, on "how to prepare financially for a layoff," it would be nice to be able to---without changing the budget I currently have active---create a second parallel budget based on different assumptions, so that (for example) if I were to be laid off I could immediately switch to a budget I'd already prepared for that contingency. This feature could also be used to plan for an expected wage increase without starting to implement that plan until the increased wages begin.
