If you want to set up the option to re-assign sign offs to other people, we provide a hidden feature to allow you to assign proxies.
In the DOC configuration setting you can specify a list of users or user groups, who can change the users that need to sign a document, by adding a property "proxyRights" to the advanced settings.
If this list is defined, a proxy button is displayed in the SIGN item behind each user, who still needs to sign.
The manager can now choose another user not yet in the signature list to delegate the signature to. The other user can then sign the document on behalf of the original user.
