Sync related issues

How to operate the lower UCP204.1 will not synchronize the upper UCP204.2
I'm modifying lower level UCP204.1
The upper UCP204.2 will be modified together, which is not what I want

The part UCP204D1 Housing is instanced in both assemblies, so changes made to the part will occur in both assemblies.

Copy the part and save the copy with a new name, and then replace the part in one assembly with the copied part. Each assembly should have different parts.

Also copy the assembly and save it with a new name also. Again replace the assembly with the copied one in the higher level assembly
