Is it possible to model from a polyline based on an attribute?

BenHenderson

I've got a single polyline that outlines many disconnected segments of siderite mineralization drawn from dozens of underground face photos. I would like to group some of these segments together into a wireframe as the basis for a small geologic model of boudinage. I know that I can select each segment and assign it a particular attribute (say a boudin number), but when I make the GM, I don't know how to filter it to use just a particular attribute instead of the entire siderite polyline. Any input would be great-thank you!
