That's not how Alamode works. It becomes locked when any signature is placed on it. If ANYTHING is attempted to be changed in the report, a pop-up will warn that the signature will be removed if you want to alter something. As long as the supervisor doesn't change anything, it will allow a supervisor's signature to be placed on it without unlocking it. If the supervisor wants changes made, s/he can do that and then send it back to the appraiser on the left to check over and add their own signature again.
It is NOT 'industry' standard to allow others access to your digital signature!!!
It is NOT USPAP compliant to do that which makes it against the law in most states.
The 'everybody else is doing it' is NOT a legal defense!!!!!
If your software doesn't allow it to be set up like this, you really need to think about getting a different software.
