Date to auto-fill +7 days

Hi everyone,

I am not sure whether this require scripting or it can be done via the admin.

Let's say that I have this 1 document class and in this class, I have a property "due date".

Normally, when we wanted to create a document of this class, we need to manually specify the date. Is there a way in which we can auto fill in the due date so that it will be next 7 days ? 
For instance, if I create the document now, inside the metadata, the due date will be displayed as 24-May-2023. Of course, the user can still amend the date later if require any changes. But normally, all the due date should be next 7 days.
