How to update custom field value for all the existing subscriptions

Summary:

Hi,

I have created a custom field at subscription product level using sandbox, Is there a way to update the newly created custom field at product level column with value from another custom field at subscription header level.

Let's Say...

If at Subscription Header Level Custom Field Value is "A" then I want the same value to be updated for all the lines of that subscription in the new custom field, I created at Line Level.
