Auto-sync Google Slides when Presenter opens a service

It would be very helpful if any Google Slides within a service get automatically downloaded (or synced if previously downloaded) when the service is opened with Presenter.
At the moment I have to click through each Google Slides item in the schedule and wait for it to download before moving onto the next.

The same goes for YouTube videos. It would be nice if they could automatically be buffered when a service in Presenter is opened, so they can play immediately without loading delay.
