Pass constant into drill through

Hi is it possible to pass a constant from a dashboard into a drill through parameter. I want to set an action on a table to navigate to a drill through table that has a number of parameters. I don’t want to pass a data value from my dashboard into the drill through table I want to pass the constant value of ‘On Target’ to my target status parameter.

Can you make a parameter on your dashboard that you set to ‘On Target’, but don’t show to the users?
Put it off the canvas somewhere, but it still exists and you can set it up in the drill through.
