Can I Turn off Auto Execution of Report when all parameters have default values?

My situation....

I deploy a report in Report Server. Ther report has 5-10 parameters. When I design the report, I supply a default value for each parameter, similiar to the "Add a select all option" tutorials.

So I end up with defaults like "Select a Project Manager", "Select a Fiscal Year", etc... I use dynamic queries to read the parameters and insert the appropriate logic into the where string of my main dataset. If the user selects a value from my parameter lists, I append a clause to the SQL string, if they choose the default option, I ignore the parameter, and that effectively returns all of the records (like Select * from ....)

My Issue...

When I provide a default paramater for ALL of the parameters available, the report auto-executes when the user picks it from the folder, and isn;t given the opportunity to refine the default criteria I have provided.

My Question....

Is there any way to turn the autoexecution off?

Thanks for any help...

There is no method to turn off the auto execution of the report if all parameters have default values.

As you have probable already found out, you can populate all but one of the parameters to get the result you desire. But that makes the user have to supply a value of the parameter.
