I understand Geoff's point. We want to be informed by what we hear, and then that informs how we call witnesses.
What I imagine to happen, Geoff, is that if we submit all our witnesses by next Tuesday, with a bit of research, we'll have a pretty complete picture of what we're studying. If there's a desperate need for another separate issue, then I think the committee would just take a pause at some point through this study and say, “Issue X hasn't been identified at all; will the committee hear another day or tack another meeting on during the week?” I think that makes more sense than leaving us in ambiguity of the witness list not necessarily ever being closed.
