Flipping the clip horizontally without changing the position

Hi
I’ve loaded a clip in my main swf and I want to flip it by using scaleX*=-1
the problem is that in my clip, the animation is at the center of the stage so when I load it and flip it using scaleX instead of staying at the same place it flips by using the top left corner of the clip as a pivot instead of the center of the animation itself

I could either solve this problem by placing the center of my animation on the point (0,0) in the clip or flip then rearrange the clip’s x position inside my main swf…but is there a more effective method?

thanks
