I am often routing contracts prepared by another employee for signatures. When I use 'Request E-signatures', Adobe automatically detects form fields, including fields that have already been completed and should not be edited by any of the signers.

Currently, I have to right-click on each form field and manually change 'Assigned To' from the dropdown list to myself/(prefill). Why is there not an option to set a default for the 'Assigned To' field or allow users to change multiple form fields simultaneously?
