Allow download of redacted copy of completed agreement

I (as well as lots of other people on this forum) have the need to collect PII in an agreement, but also need to distribute that agreement to people that do not need the PII.  We must limit who has access to the PII so It would be super helpful if you could flag fields as PII and then have an option to download a completed agreement as you normally would, but also download a copy with the PII properly redacted for privacy compliance. 

I wouldn’t even care if that copy watermarked “REDACTED COPY” or something like that..or even lacked the digital signature.  I need to be able to grab this redacted document via the API.
