How to indicate fields which a field which will be retrieved from the server after save

I am working on an app which is available on desktop and in ios. Our users are used to this option on desktop where the last filled in value for a particular field will be used for the next form as well and its prefilled , so they do not need to fill it out again.They can select on desktop which fields they want to use it this way.

What is the best way to indicate these fields on ios so user is aware that they do not need to fill it up. We decided we cannot retrieve the value from server and display currently, but just indicate to the user that upon saving, the last saved value will be saved for this form too.
