PAI installer

I dowloaded this and it done exatly as i wnated i to. BUT when i had a look in the note pad at aircraftt goes from 200 to 1100 if i change thses to 201,202,203, would it make a difference or should i just leave them the way they are. I know hat i i change them then the a/c number in the flight plan would be different. I just realy want to know if it will still work if they dont go in numerical order? Thanks any help would be smashig.
