Quick AMR Question

I have 3 spun articles, now i want to feed these to AMR so during submission it picks one randomly.

Do i have to use TBS to spin them together and then paste them into AMR? but then the body may not fit with the excerpt if each contains 3 versions ?

How to do this?

Thanks

Just submit each article individually.

As SEOWhizz suggested you should send them individually using the scheduler only to 1/3 directories and not the whole database.
