You can assign a signature configuration to a specific individual if required.

First, create a new signature configuration document. Then under "Who is this signature for?" make sure that "Group" has been selected, and finally using the textbox, type in the name of the user.

The following appears in the Signature design.

NOTE: The signature configuration documents are processed in the order they are displayed and only one signature configuration can be applied. If the user is a member of a group that is listed BEFORE, the user's signature configurations document, the group signature configuration will be applied instead.
