How are documents ordered when mass generating them ?

Hello, On some objects, we have a document template being used. We can generate them for each record, or mass generate them using a "Template document" workflow action and checking the "allow this action for group of records" checkbox. As it seems, when mass generating them, they are ordered by "record name" ascending when it's a ".doc" template, resuling in one .doc file. However, when it is a HTML rendered as PDF, they are randomly ordered in the resulting PDF file. Can you see why? Also, could it be possible to have them ordered as they appear in the view? (Which means, using the ordering configured in the view) Instead of having them ordered by record name? Thank you, Best regards. Romain Pennes.
