Multiple one time only signature fields
I am creating a document which is more or less a process with certain steps.
What I want is that after each step inspector will sign the document. So one person will be signing multiple times the same document. This is not an issue so far.
In addition to this, I want that once inspector sign the document, this signature becomes read only or unchangable. I could not figure out the way to do this. Is there any option for one time signatre only after it is signed while other fields will still be active ?
Thank you fopr any help.
