There already exists a system within the corporea sparks that allows a player to specify networks with floral powder so that multiple systems placed in proximity with each other don't interact in the wrong ways. I think it would be useful to be able to do this with regular sparks as well. Having multiple constructs in proximity to each other that both use sparks can be a pain, and the only way to avoid it is to build them further from each other. It would be a nice feature to be able to specify what sparks a spark can and cannot interact with via methods other than spark augmentation, as things such as the isolated spark augmentation completely cuts off a spark from all other sparks, not just certain ones.
