how set part path when option 'Auto-connect parts to CAD document' is selected

Hello

I set the storage path of the CAD document to the folder A and checked it in.
At check-in, I chose to automatically connect CAD documents to parts as an option.
CAD documents are stored in folder A
However, auto-connected parts are stored in root.
How do I put the path of the auto-connected part together in the folder where the CAD document is stored?
If you use object initialization rules, you can only assign one path at a time?
I want to store the parts connected to the folder where the CAD documents are stored flexibly.
Thank you.
