Yeah, so Zach the sales journey here is both from a new business global sales organization perspective, as well as an account management and add on basis, both of those are critical to our future and our success. Think about probably two thirds of the TCV is coming from the GSO longer term, kind of sales organization, global sales organization, and one third from the account management and add on. But the inverse is true when it comes to impact revenue, we're saying year revenue where two thirds of the impact revenue is coming from those account managers in that add on revenue. And one third of the impact revenue, even though the ARR is higher, is coming from the global sales organization. And so what we've been doing in our journey has really been about leadership, about discipline, about oversight, about focused concentration on sales. We're going to finish the year, worried about 110 sales exits, today 109, 110, we expect to launch into 2021, with about 120 with constant sort of improvement across the sales force resident along the way and into the future. And so we see some pretty consistent performance coming out of our sales force. In the investment, if you're alluding to investment within sales, as opposed to investments writ large are really now, we think between 120 to 130 is kind of the right mix given our portfolio. The new investments are going to be more around training, around training protocols, training software, training discipline, and consistency around account management and portfolio management. So it's a journey. It starts with talent, it moves to process and within that process is some of the software that I just discussed. But if that's the investment you're referring to, that's kind of what's next for us.
