Hello Everyone

In the Summary Information window and under the Configuration Specific Tab.  I want to add the string \$PRP:"SW-Title" to the Pull-Down Menu for the Value/Text Expression Column.  Then it will be available to me all the time without typing the string each time.  I do not see where to add the string so it appears in the Menu.  How do I add the SW string to the Pull-Down Menu?  Thank you for your assistance.
