Configure bounce animation instead of glow

Hi,
I really like plank,
after long time with cairo dock I installed plank in order to check why I moved to cairo.

So the only one thing that bothers me is that the notification animation when plank is hidden,
I would like to be able to configure that the animation will be a bounce animation instead of glow.

I tried to look how to configure the animation but haven't found it.
checked in the plank preferences GUI,
checked in: ~/.config/plank/dock1/settings
checked in: /usr/share/plank/themes/Numix/dock.theme (I'm using the Numix theme..)

I could not find the option to configure the animation in amy of the places above.

Please add the option to control the animation,
or please explain how to configure it, if the option already exists and I missed it..

Thanks for the help,
you are awesome and continue the great work :)
