How to pin an MS Office file to start screen (W10M - build 10536) ?

[FHilario]

I had a folder in start screen with some MS Office files (wp8.1) ... But after migrating to w10m build 10536, they are gone .... I tried to pin the files from One Drive folder too, but no success.

There's an way to do that, and keep the files sync'd wherever I open them ? (I don't want a plain copy)

Thanks and Regards.
