Prevent certain xref's from checking into vault from autocad

[Thomasbatson]

I am looking for a way to prevent the check in of certain xref's.  I am trying to use xref from autocad for a signature on my drawings but I don't want that signature to get checked in so no one else can "get" that file and view it.  I tried to use the file type restriction in the Vault settings which work if I drag and drop a dwg into vault or use vault, but if I use autocad to check in a drawing it will grab the xref and check it in.  

Does anyone know how this can be prevented?  Thank you.

This article says it is currently not possible:

If this wasn't about a signature, but simply a geometry/drawing XREF, I would recommend setting those under a folder you could control permissions to not allow it to be read by most. But since this is a signature then yeah you don't want them being shared at all. Some more info here on setting up a library for XREFs:

That article led me to what I was hoping to accomplish. What I ended up doing was creating a "seals" folder in vault, adding the seals and signatures for everyone in that folder and applying certain security assignments to the folder.  Then for each signature I went into details and assigned only the user of that signature security access that signature.  

I have tested this with a sample project and works great.  Thank you for the link and information.
