MV library 23.0810

Build 23.1.811.641

I would like my Base corner cabinet to have a Susan shelf depicted in the CAD, but I am having a hard time figuring out how to do this. I have found the dwg file for it, but not sure how to link it. I was also wondering, if I would have to create a formula for MV to pick the most appropriate size seeing how there is more than one to choose from.
