Is it possible to make the module "FileFiled Sources" compatible with "Field Collection" ?

Hi,

I m using the module "field collection" to upload files. But I need to be able to select or browse files already existing on the server.

In fact, Field Collection seems to allow only uploaded files. If a file already exist (ex: myfile.pdf), then the new file uploaded is duplicated (ex: myfile_0.pdf). Is there a way to select an existing file on the server (ex: select the myfile.pdf instead to upload it again) ?

I saw the module "FileField Sources" who make possible to browse existing files. But it is not compatible with Field Collection.
Is it possible to make them compatible ?

Thanks
