Autofill multiple fields

Hello everyone, I have a question to which perhaps there is no answer. I have two fillable pdf files: these are documents for privacy and for delegation. In both fields that can be filled in are the same: personal data, residence etc ... When I work, each client must sign them both. To fill them in, I have to enter the same data twice in different documents. I was wondering is it possible to merge them and make sure that the data copied in one page is automatically reported in the other as well?
