Yes. And I would point folks on the call to our Analyst and Investor Day presentation where we covered the sales force expansion plans, the pre-approval sort of medical and marketing initiatives and so on. And so, I would say, Jeff, the current activities kind of fall into three buckets. You have disease state awareness ahead of a product approval, and that campaign was launched at the American Burn association meeting this past year, virtual meeting, and that will continue ahead of launch. We have, obviously, brand development that is ongoing right now. And then, of course, market access initiatives, as well. So, all three of those buckets were sort of laid out by Roland on our Analyst and Investor Day call. It's kind of the typical sequence of events you do ahead of launch. And so there's a lot of those activities. Once the BLA has been filed for review or accepted for review by the FDA, that you kick those initiatives off. So we're deeply engaged in all of those activities. In terms of the sales force expansion, we currently have one national sales director and 11 sales reps and clinical support specialists. So as you think about getting towards 20 sales personnel, that's a little difficult for one person to have that many direct reports. So, we'll have a structure that again, is much like our MACI structure in terms of we'll have two regions with two regional managers, and then essentially 11 territories that are supported by both reps and clinical support specialists. So, we think that's about the right number to call on the burn centers, which is the next part of your question, which is sort of right now, as I mentioned, we probably focused on the top 80 burn centers out of the 140 in the country, because those are the centers that typically see sort of the catastrophic burn patients like the Epicel patients are, so not all the burn centers routinely will have Epicel-appropriate patients. So, we do focus on sort of the upper end of that. As we've talked about before, virtually all of the 40,000 hospitalized burn patients across those 140 centers are going to need some sort of debridement. And so, NexoBrid will allow us to focus our efforts on a broader set of the burn centers. And as I mentioned in my prepared remarks, we certainly expect that will provide opportunities to increase Epicel uptake in those centers that don't currently use the product. So, we do think there will be a lot of synergies there in terms of the Venn diagram portion of your question.
