[Chiuso] How to sync the custom post meta field in other languages

Background of the issue:
I am trying to sync the custom post meta field in other languages on my site link nascosto. My custom post meta field is digital_asset_json. I want to translate the label but not the link associated with it.

Symptoms:
If I choose to copy the custom post meta field, the label also gets copied, which I don't want.

Questions:
How can I sync the custom post meta field in other languages without copying the label?
Is it possible to translate the label while keeping the link unchanged?
