Rename linked file in arbitrary directory, without changing location

[sancho-s]

I often have Zotero items with linked pdf files as attachments.
The location of those pdf files is a directory of mine. Not a Zotfile directory, nor a Zotero directory.

Is there any way of renaming the linked files as per Zotfile rules, but without changing their location?
The closest to this I found is:

1. Right click -> Rename File from Parent Metadata.
   But this uses Zotero rules, not Zotfile.
2. Right click -> Manage Attachments -> Rename and Move.
   This uses Zotfile rules, but it also moves the attachments to Zotero/Zotfile directories.
   I want this, without the Move part.
