SSRS Cache Reresh plans with parameters

Hi

Sorry this may be a very basic question, but I am fairly new at SSRS...

I have a report that has multiple parameters and returns large amount of data, which makes reporting execution slightly slow.

I understand the concept of caching and snapshotting the reports, but I am a bit confused to set it up when this report has parameters that the end user selects...there are about 70 odd items in one of the parameters. Does this mean I have to create 70 cache refresh plans?

Thanks in advance!
