Disallow rule and module density?

@Jan Pernecky and monoceros team. I was able to resolve the previous problem with my file. Thank you. I encountered another separate challenges this time. 1) the solver didn't follow the disallow rule even though I have connected them correctly (I think?) Is it because It needs to fill in slots that it overwrites the disallow rule? 2) Is there a way I can control the density (i.e.20% or 30%, etc) of each module in the output? We do want to follow the result in the attached image. I can also copy this in the forum. Just let me know. Thanks.
