how to save specific features to the library??

Is there a way to highlight and save a certain feature to alibrary?
for example if i want to highlight a threaded hole that has a oring groove at the top ( a port fitting ) . is there a way to savethe modled configuration in the library so that i can just applieit to a boss or any other componet?

for example i attached a file with two of these port fittings thati want to have readily availble.

is this possible?SolidworksToolbox
