I’ve also been thinking about this feature, and was about to add something similar. What Ankush describes is probably more flexible and easier to use.

I was thinking about having expenses optionally depend on Milestones, and add the ability to toggle off and on milestones themselves, which would then automatically turn their dependent expenses off and on.

But what Ankush describes would allow you to roll-up exactly which expenses depends on a specific decision variable, which could comprise multiple milestones, or parts of many, and other life events. So this approach seems like a better way to go, more all encompassing. Although maybe for visual clarity on the chart you could have Milestones depend on Decision Variables, such that you could hide them.

e.g. you could have “Get Married” as a decision variable, which would have expenses and milestones associated with it.

And you could have Decision Variables depend on other decisions variables. e.g. You may want to say “Have a kid” Decision Variable, depends on “Getting Married” == true. and “Adopt a Kid” decision variable, depends on Getting Married == false. And of course each of these decision variables could have numerous different dependent expenses.

I would also like to see House assets be able to depend on these Decision Variables. e.g. “Have 1-2 kids” makes us choose a specific House asset, vs. no kids, or 3-4 kids.

Even cash-flow priorities might make use of these Decision Variables.

It’d be helpful if decision variables could depend on other decision variables. Example:

• Decide to buy land.
• IF bought land: Decide to build a rental unit

More on this: some decisions depend on having taken other decisions, and some decisions preclude other decisions.
