Modifying a Signed Document via its Metadata

Question

This is a good one for all of you out there. We all know that if you make a modification to any Office document that has been digitally signed, you end up removing all signatures in it because the file has been altered. However, we have a scenario, where
content in our Word documents are imported out of a SharePoint list. For exemple, we have a form that will initiate a new Staffing request with our HR department. The information related to the linguistic profile of the position to staff is extracted out of
another SharePoint list.
If someone was to sign the document, and then go and alter the linguistic profile value in the associated list, the new value would show up in the signed document, preserving the digital signature. This gives the impression to our end-users that people are
able to alter Office Documents that have been signed, and is making them loose faith in the platform. I am looking for advise or recommendations on how to best approach this issue to ensure people cannot altered external data that is being used by signed documents,
or for a way to have the digital signature removed if the data is ever modified.

Is there an Action Wizard to automate this? I have partners that chance the file name,  what I would like to have happen is the orginal file name becomes the title, so if the file name gets changed the title remains the same.
