Refer an interactive poll/brainstorm slide
I would love to be able to refer to a earlier poll, or another interactive slide, later on in a presentation. For example - say I invite my group to brainstorm ideas... we got through a bunch of other information and then revisit that slide to show folks what they said.
I would have put that placeholder slide in creating my presentation and when I get to that placeholder slide it would be populated with the responses folks gave 20 minutes before.
