saving a library feature in a part

We have a manifold block with about 30 ports in it that areall library features. The user that created these doesn't work forthe company anymore and I want to reuse 1 of the ports on anotherpart. I can drag and drop it but I get a ton of errors.

Is there any way to save the library feature to a folder or am Istuck...?? I was hoping the feature had a reference location (file,find references) but it doesn't
