Can I specify my own growth rates and risk assumptions on Timeline for my model portfolios?

Yes. On the Snapshot screen, click on “Monte Carlo” and that allows you to set the expected return (Mean) and volatility (Standard Deviation) for inflation (bottom left of this screen). If you then go via "Plan Settings"/"Portfolio"/"Edit Portfolio", you can enter your return and risk assumptions for investments - either at the portfolio level (specifying a single growth rate for risk and returns respectively) or at the asset class level, by changing individual asset class returns and standard deviations.
