This field indicates the presentation support that has been entered during the initial definition of the target. This support will be reused by default during later inquiries on the same target.
But the user can freely decide to use selectively another support to carry out an inquiry on the contents of the sample. The user is helped with this by an associated selection list or via a tunnel on the presentation support management object.
This field also has available a contextual menu named "Personal preferences". On using this menu, the user sets his permanent personal preferences in terms of the presentation support for the current target. In this manner, the same presentation support will always be suggested by default on the creation of each new target defined by this user.
