Functionality inside Powerpoint to switch all PowerBI embedded pages/visuals to Public Snapshot at once.

Love the new functionality of being able to switch visuals connected in Powerpoint from PowerBI to Public Snapshot from Live. However it would be great to be able to be able to somehow switch all visuals to Public Snapshot or back to "Live" .

We have monthly presentations that we would like to lock and not have updated until the next month end and then be able to switch to Live.

This will improve productivity of users.
