Yes, but it wasn't efficient as a solution. in fact I'm using this to prepare my document:

Could you post this topic on the english forum (http://project.auto-multiple-choice.net/projects/auto-multiple-choice/boards) ou french ?
I'm afraid you can't do this. AMC needs the barcod and the four marks to detect the boxes and the borders may disturb this.
