I need some help on wet venting

[Daniel Michaels]

I need to know how to vent this house as it is slab on grade and I need to know which walls I should use to vent it. There are two bathrooms, a kitchen sink and a washing machine. I also want to plumb for a future bath in the upped room over the garage. The house is 2x4 construction with perimeter continuous insulation. I'd like to keep the vents out of the exterior walls. I understand the tee's and pipe sizes. I was wondering if there was a better route or maybe less messy way of doing it. A licensed Plumber will do the work but I need to know where the pipe is most likely to go so I can create a plan. This is UPC for WI.

Thank You for any help, Dan
