Mods: Stackable Go Here Interaction by abidoang from Mod The Sims.
This simple mod overrides the “Go Here” interaction that you can use when you click on terrain so they can stack with each other. Usually, if you stack more than one “Go Here” interactions, the first “Go Here” interaction will be automatically cancelled. With this mod installed, you can now stack multiple “Go Here” interactions and your sim will go through all of them. This mod is perfect if you want to manually route your sims.
