MDT supports a special type of session, called Session Link, that enables running a session based on existing aliases. New Session Link wizard allows you to create many sessions at the same time. The choice of aliases, which are a base for creating sessions, is supported thanks to the definitions of products stored in LAYERED_PRODUCTS file. To start the Session Link MDT uses the application launcher (gis.exe) that has been given in the Runtime assigned to the session. In addition, Session Link editor allows you to customize: image file, working directory and session launcher parameters.
