A table of the shared parameters will open. To add a new shared parameter, it has to be marked as **Selected** in the last column. The rows of selected parameters will be displayed in green. By default, the new parameter will be added as a 'Type' parameter, and the user can select it to be an 'Instance' in the table. The parameter group must be chosen as well.
