Remove Material in the Operation

How do you remove material that is attached to an operation, but not remove the material completely itself using DMT?

Story time: One of our engineers engineered many, many, many parts and put the material in the print operation AND the Figure operation. Figure is no longer useful and needs to be removed. However, because there is material attached to it, we cannot. So I need to remove the material from Figure but leave it in for the Print Operation. And, because it is so many parts, be easier if we could use DMT for that. I have tried and it keeps trying to remove the material out of the entire job.
