Force pdf download only for some documents or categories

Hello

I'd like to force mime-type (force to download pdf instead of opening it in browser), but only for some documents or some categories, not for all the pdf.

Is there a way to manage it? (I've seen there is this option in the global configuration of edocman, but my need, would be to manage it on a category of documents only)

Thank you for your feedback

Hi Romain,
Actually, Edocman calls the Download function to download document, but in case your desktop doesn't have download software like IDM and your browser support documents reading, the document will be opened on browser directly. But this is very rare.
Thanks
