Park within a cue

Here's what I'm trying to do:

I have dancers at the club I work at. I'm using a 250 to light them while they go up, using a cuelist. I black out the board often, and would like to have the intensity parked even when I bump the master blackout.

As it stands I have to hit the cuelist button, then select the fixtures and park their intensity. How could I make a single button that moves the 250 into position and then parks its intensity while the cue is activated, and then removes the park when the cue is released?

Much thanks
