Stop “animate param” Puzzle and reverse it?

Hello,
I have a questen about the “animate param”-puzzle.

My target is, that I want to start the parameter animation with a html button and if you press the button again it reverses the parameter animation.

My solution is, that i have two “animate param”-puzzles.
One for open and one for close.
I check the status with a “is open” variable and then I trigger the correct “animate param”.

It works perfekt until the use presses the button in the time it animates.

Now my question is:
Is it is possible to interrupt the puzzle and reverse it from the value it was interrupted? So I would not neet two puzzles.

I hope I have explained my probleme understandable.

thank you
