How2: Lock instancename for working in current swf

Hi,
Is there a way to lock instancename in a swf to prevent it conflict with other swf, when they are loaded in mainmovie.

Say I have this string: in both b.swf and c.swf. And they are loaded up at the same time in a.swf.

loadMovie(this.pathToPicsJan+this.pArrayJan[0], _root.photoJan);

Somehow the mainmovie get confused with the instancenames. Is there a way to get around with this so I don’t have to rename each name?? It would b such a hassle to rename all instancenames if I got many duplicated/similar swfs.
