Let's say I have 60% of my portfolio in stocks (maybe VTSAX) and 40% in bonds (VBTLX). Is there a way to model selling only the bonds when the stock market has a major decline? Then rebalance when the market recovers?

I can't think of a simple way to do this. The simulation engine doesn't know about/understand asset allocation. It just takes a return and standard deviation as inputs. Also, there's no way to dynamically adjust the return/std deviation based on a market crash.
