Disable Upload functionality on Prezi Desktop

We’re looking at offering prezi as a solution to our staff however we (IT department) need to be able to disable the functionality of the Prezi Upload feature as this poses as a risk. Is there anyway we can disable this upload function?

Looking through Prezi there isn’t any options or setups that could be reconfigured.

Yeah, as much as we’d love to release this to everyone… there are a few things that we’d need to address prior to.

So basically I want to make sure the user can only create local Prezis not the Synced with Prezi option.
