Excel and AmiBroker integration

I was wondering if it is possible to do this...

Lets say I draw trendlines (up and down) from a particular date (high or low) to another date (high or low) in Amibroker...

Now.. I load an indicator (or whatever it is called for Amibroker) and link an excel file to it..

then as I draw the trendlines (up or down), I want a few cells to be highlighted red or green...

Is it possible to do this ? If yes, I would like to know how ? Can anyone of you write this for me ? How much it would cost ? I am willing to hire a programmer who can do this for me...
