Is it possible to restrict the “Extra Margin” under the Grid to particular sides of the grid? I have a truck moving along a dirt road, and the dust trails behind it. It doesn’t need to expand near the hood of of the truck, just a bit on the sides, and a lot towards the back. Is it possible, or would it be possible in the future to say something like Y+: 10, Y-: 50, Z+: 40, X+: 20, X-: 20? Would help cut down on some of the simulation time if we could do that. Thanks!
Can’t find out how to delete this, but I think I found it 
Indeed, sounds like you were looking for the adaptive limits
