Update documents property from parent

Hello,

 

We have a project object with a country property. Ex Object CT21007

 

Documents are then linked to this project object by contrat(s) property and the country property is inherited. Exemple document linked to object CT21007

 

If I change the country on my project, is there a way to upadate this information on all the documents related to the project?

 

Regards.

Thomas
