After playing around with Sparks that there is no way to have only some sparks interact with each other. So for example I use sparks for my main managen and for my livingwood/stone production but I don't want the sparks to interact between these. My suggestion would be to be able to dye the sparks to make them only interact with other sparks of that color.

I'm not interested on that, the lack of ability for multiple networks works as intended.
