SSRS Cascading Parameters

Dear Team,

Kindly help with below issue.

My SSRS report has 8 parameters among which first 3 are mandatory and other are optional.

I have 6 datasets 1 for main report display dataset and other five are for cascading parameters dependent on first 3 params.

cascading params are initially disabled as there dataset uses mandatory params.

After entering mandatory params the cascading params are enabled 1 by 1 and not all at same time.

Is there are way to enable all cascading parameters at the same time as there is no dependency among themselves and all 3 mandatory dependent fields are already populated.

Thanks!!
