How to push updates from root to prefab.

Hello Everyone,
I imported an assembly with several parts in it. Then I saved it as a prefab and changed the colors of all of the parts. Now I realized that I didn’t enable colliders on the original assembly, so I selected it and turned on colliders, but my prefab doesn’t change…still no colliders. Is there a way to push the changes of the original to the prefab, or will I have to create another prefab and spend a ton of time changing the colors again? I’m using 2019.4.29f1
Thanks!

You mean asset? Assembly refers to DLLs / scripting.

Check if the object in the scene has a prefab override menu at the top. You apply changes made to a prefab instance in the scene via this menu back to the prefab. For more info check the Prefab section in the manual.

Sorry, bad terminology. It was a SolidWorks assembly, so yes, an asset. I checked the override menu, but it doesn’t show any. I’m assuming that only shows changes that were made to the prefab while it is in the scene?
I tried unchecking and rechecking this and it looked like it reloaded the original, but I guess it really didn’t since there’s still no colliders on the prefab.
