EZWYOBuilder

I did and still having trouble. I am a builder more than anything, I am new to this software and feel it could be very valuable once I can fully utilize it. What I was hoping for was, for example. On a wall that is knows the amount of lumber and drywall and trim, is there a place I can enter a value for the 2x4, sheet of drywall and cost of trim and it gives me the cost in the materials list. Right now the only way I can do it is go threw and enter the value each time it shows up for every individual wall.

How do I add a cost to building materials to have it show up in the materials list? What I am asking for example, Could I put a price on a 2x4 or a sheet of OSB and have it consistent throughout the materials list every time that object occurs
