It would save a lot of time if you could just click a break point button in the main toolbar while a fixed resource is selected (in both the model and process flow). Most of the time when we set breakpoints on specific lines of code within the triggers, we just need the model to stop while the entity is physically present so we can debug flow, processing, and label issues. Setting the break point on a specific line of code lets you be more specific on when you want it to stop, but is usually unnecessarily specific and time consuming.
