Parameters Disabled with Snapshot Report Execution

Is there a way to schedule report snapshots and still give users the option to change the parameters? I found that report parameters are disabled when I set the execution options to use a snapshot. I fixed the problem by setting the report to use cached data that expires on a custom schedule and by scheduling an e-mail subscription that creates a new report cache soon after the cache expires. I'm guessing there must be a better way to provide good report performance with the default parameters as well as flexibility.

You'd need to change from using Query Parameters the query to using Report Filters.

I would only recommend doing this for filtering relatively small amounts of data. The SSRS is not as efficient at filtering data as a stored proc on a DB server.
