The QR code shows on the introduction slide. Users needs more time to get out phones etc. Please add function to show QR code on regular question slides (see attached image). I can add QR by manually doing screenshot, but I copy a lot of my presentations and so have to update all these slides otherwise they have wrong QR code. Please please please add ability to show QR code on slides (in lieu of adding image). Thank you! This will be enormously helpful.
