Uvision and using Unilock patterns or components in SketchUp


I am a Landscape Designer using SketchUp Pro to show clients 3D landscapes. I import 2D designs from Dynascape and I use their component add ons. Some of my installers would like me to utilize the Uvision - Unilock program. I pefer to only use SketchUp, but would like input into how other designers add the Unilock pavers to their patios. I downloaded the DS Paver file and saved it in Materials. Is anyone familiar with importing more specific Unilock patterns, colors, soldier courses, seat wall components, etc into SketchUp? I think the installers want to demonstrate the specific brick types, colors etc.
