No - you cannot manually tweak clones in the eco-system. However, you can control placement in many ways : - with a density function, procedural or bitmap (useful for the shape and size of clusters) - with the help of 'foreign' objects. You can place objects around your scene, generate an ecosystem that will avoid those objects, and then remove the objects. If you want to tweak particular instances, the only solution is to either replace them by a single copy, or maybe by their own ecosystem material (with that particular setting you want).
