title: SSRS - How to add a default value to a parameter with Available Values from a query?
body: <p>I have an SSRS report which contains a parameter ID, which will display sales totals for a person with selected ID. I get the options for the parameter by selecting "Get values from a query" under the Parameter's "Available Values" setting. However, in addition to these values, I want the first (default) value in the dropdown to be "All", which will display results for everyone combined. How can I add this hard-coded default to the dropdown list?</p>
