Disable Save to disk option

Hallo Community,

I wonder whether it is possible to disable the 'Save to disk' button in the 'Save Document As' form in Microsoft Office. Intention is to force our users to save documents only to ProjectWise. I guess there's no option in ProjectWise, but maybe with the SDK?

Does anyone have experiences with that issue? Currently we're using PW Explorer V8i (SS1 and SS4).

TIA,

Maik
