Toggle slate frame

In some circumstances, the Versions we upload include a slate that we want to be able to see when viewed on the SG website.
It looks like if we have the “movie has slate frame” checkbox ticked, then the web player clips the slate frame off.
Is there a way to toggle this behaviour on/off? I don’t want to uncheck the “move has slate frame” field to be able to view the slate as that’s a bit of a hack.
