Change Report Parameter Dynamically based on other parameter (MDX parameters)

Hi,

I'm looking into the possibility to be able to set a parameter value based on another parameter.

Let's say we have parameter 1 which is a boolean "Only CS Projects"

Only CS projects means, select all projects with Main ProjectID = "CS".

And offcourse parameter 2 which is linked to the Main Project ID field.

There are tons of projects so manually selecting the "CS" mainproject in parameter 2 isn't an option.

So to keep it simple for the end user, I would have liked to add a checkbox to add this filter.

Any suggestions?

Regards,
