Hide columns with multivalue parameters

Hi guys,

i want to hide some columns in my report by using multivalue parameters. I have got 5 fields with sums for: hours, special-hours, amount, performance and cars

I would love if multivalued parameter would be structured like this:

Parameters!myparameter.Value(1)  could stand for hours
Parameters!myparameter.Value(2)  special hours
......
Parameters!myparameter.Value(5) cars

And afterwards I could set the visibility for the column with:
Hidden = Parameters!myparameter.Value(2)

So when the user clicks the "special hours" on the multivalue parameter,
the column for special hours would be invisible.

Would be nice if it was that easy, but I guess it isn't.
