Hi !
Everything is in the title : is there any way to attach the same file to several references at the same time ? Instead of attaching the file to every references one by one (which can be quite long when I have a lot of references…)
Many thanks in advance ! 
Well, I know it seems strange, but I sometimes have a lot of references which are related to a single one PDF. So I want to attach this file to several references, but if I drag and drop it, it will only attach it to one reference. Or, as I have a lot of references, it is quite long to make it one by one.
Hope I explained it well this time
