Changing components with replace

Hi def components from the warehouse show down work tremendously. can they be changed to replace me components?

Hi-Res comp to ‘Face me’ (2D) comp and back


After selecting the hi-res model in the viewport, right-click in the Components panel on another component (a low-res one)) with which you want to replace the hi-res model, not on it again.

that did it! THANKS SO MUCH! My model was getting painfully slow!
