Just a thought: we now have a checkbox step that already let every user propose their own consent form already.

yes!

The consent tick box should have a customizable field where the host can write what the guest is consenting to. In my use case, I sue the audio to create transcripts, ebooks, articles etc. My guests need to consent to their interview being used for wider distribution purposes so I need to be specific about what they are agreeing to. At the moment, I have a step where they read out and record my consent message. A tick box would be great.

Another great idea
