Can loadmovie command be cleverer?

Hi Im really Stuck,

I have this movie http://urbanjackal.members.easyspace.com/visionco/ its for a mates building company

ok here is my problem (i will explain it to the best of my abilites)

i have 3 buttons which each load 1 seperate SWF into an empty movie clip
eg. servicesbutton loads services.swf into contentsMC

that is fine that is working fine my problem occurs when the loaded movie button is clicked on again… it resets the loaded SWF back to frame 1…

how can i make the loadmove command abit more cleverer? like dont load the movie if its already loaded?
